12 + UPGRADING DRAGONFLY FROM 6.0 TO LATER VERSIONS +
13 +-----------------------------------------------------------------------+
15 ACPI_NO_SEMAPHORES OPTION REMOVED
16 ---------------------------------
18 The ACPI_NO_SEMAPHORES kernel configuration option has been removed. It
19 was never part of our default kernel config.
24 The ndis(4) driver has been removed. The NDISAPI kernel option has been
25 made a no-op and will be removed at a later point in time. Users with a
26 custom kernel configuration can remove this option from it now.
28 +-----------------------------------------------------------------------+
29 + UPGRADING DRAGONFLY FROM 5.6 TO LATER VERSIONS +
30 +-----------------------------------------------------------------------+
32 BINUTILS 2.34 REPLACES 2.25, PRIMARY
33 ------------------------------------
35 The oldest of the two versions of Binutils, version 2.25, was removed
36 and replaced with Binutils 2.34. It becomes the primary version of
37 binutils and version 2.27 becomes the alternate.
39 The accepted values of BINUTILSVER are now "binutils234" (default) and
40 "binutils227". The building of Binutils 2.27 can be prevented by setting
41 NO_ALTBINUTILS=yes in make.conf
43 LIBRADIUS AND LIBTACPLUS REMOVED
44 --------------------------------
46 Both libraries have been moved from base to DPorts net/ category.
48 PAM_SSH MODULE REMOVED
49 ----------------------
51 The pam_ssh(8) have been removed from base to DPorts security/pam_ssh.
53 UTMP LEGACY API REMOVED
54 -----------------------
56 The legacy "utmp" API (getutent() and friends, utmp.h, etc.) has been
57 removed, and we are now using the POSIX "utmpx" API (getutxent(),
58 utmpx.h, etc.) only. The most visible change for users is that the
59 /var/log/wtmp file will no longer be written to, just /var/log/wtmpx.
60 The wtmpcvt(1) utility is provided to convert old wtmp format files to
63 To not break old applications, the utmp symbols are still provided by
64 libc as dummy functions that do nothing and always succeed.
66 TIMED AND TIMEDC REMOVED
67 ------------------------
69 timed(8) and timedc(8) have been removed because they are beyond
70 obsolete for setting the time.
72 LIBOPIE, LIBMD REMOVED
73 ----------------------
75 Removal of OPIE requires /etc/pam.d/ configs to be updated.
77 +-----------------------------------------------------------------------+
78 + UPGRADING DRAGONFLY FROM 5.4 TO LATER VERSIONS +
79 +-----------------------------------------------------------------------+
84 The GCC50 compiler has been retired. It has been replaced by a GCC80.
85 The default alternative compiler has stayed the same - GCC47.
88 PUFFS, PUTTER AND LIBREFUSE REMOVED
89 -----------------------------------
91 The puffs(4)/putter(4) subsystem has been removed, along with librefuse,
92 libpuffs, and the mount_psshfs(8) utility. All of these have never been
95 FFS_ROOT OPTION REMOVED
96 -----------------------
98 The FFS_ROOT kernel configuration option has been finally removed, after
99 having been a no-op since 4.9. That means users using a custom kernel
100 configuration file that still contains it need to remove the option from
103 +-----------------------------------------------------------------------+
104 + UPGRADING DRAGONFLY FROM 5.2 TO LATER VERSIONS +
105 +-----------------------------------------------------------------------+
107 DIGI, RP AND SI DRIVERS REMOVED
108 -------------------------------
110 The digi(4), rp(4) and si(4) serial drivers have been removed. None of
111 them were in our default kernel configuration file. The sicontrol(8)
112 utility was removed, too.
114 MKINITRD COMMAND REMOVED
115 ------------------------
117 The mkinitrd(8) command is removed and its functionality is replaced by
118 the new "initrd" make target. After rebooting into the new world and
119 verifying everything works, execute "make initrd" to upgrade the rescue
120 tools and initrd image.
122 IPSEC, IPSEC_ESP AND IPSEC_DEBUG REMOVED FROM VKERNEL64 CONFIG
123 --------------------------------------------------------------
125 IPsec has been removed from the system. Of our standard kernel
126 configurations, only the virtual kernel one had it. People running
127 vkernels with configuration files derived from our VKERNEL64 will
128 have to remove these options manually.
130 +-----------------------------------------------------------------------+
131 + UPGRADING DRAGONFLY FROM 5.0 TO LATER VERSIONS +
132 +-----------------------------------------------------------------------+
134 VIRTIO_PCI REMOVED FROM KERNEL CONFIG
135 -------------------------------------
137 The "device virtio_pci" line in X86_64_GENERIC has been removed. People
138 with configuration files derived from it have to remove it manually.
140 VARIOUS 'R' COMMANDS AND DAEMONS REMOVED
141 ----------------------------------------
143 rcp(1), rlogin(1), rlogind(8), rsh(1) and rshd(8) have been removed.
144 For those that still need them, there is the net/bsdrcmds port.
146 VARIOUS FORMER OPTIONS REMOVED
147 ------------------------------
149 Various former kernel configuration options which had been no-ops for
150 some time were completely removed: SYSVMSG, SYSVSEM, SYSVSHM, P1003_1B,
151 _KPOSIX_VERSION and DSCHED_FQ. Users that have any of these still in
152 their kernel configuration files have to remove them.
154 BOOTSTRAPPING LIMITED FROM PRE 4.4
155 ----------------------------------
157 Upgrading to 5.1 and later versions now require at least 4.4 in
158 preparations for upcoming base compilers updates.
160 IF_PPP, PPPD, IF_FAITH, AND FAITHD REMOVED
161 ------------------------------------------
163 if_ppp has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had
164 already been removed from our default kernel configuration before 5.0,
165 so only people with custom configurations based on earlier X86_64_GENERIC
166 will have to remove it manually.
168 The faith(4) interface has been completely removed after it had also
169 been removed from our default kernel configuration.
171 +-----------------------------------------------------------------------+
172 + UPGRADING DRAGONFLY FROM 4.8 TO LATER VERSIONS +
173 +-----------------------------------------------------------------------+
175 FFS_ROOT OPTION DISABLED
176 ------------------------
178 The FFS_ROOT option has been made a no-op and will be completely removed
179 at some point in the future. Users with a custom kernel configuration
180 can remove this option from it now.
182 +-----------------------------------------------------------------------+
183 + UPGRADING DRAGONFLY FROM 4.6 TO LATER VERSIONS +
184 +-----------------------------------------------------------------------+
186 DSA OPENSSH KEYS DEPRECATED
187 ---------------------------
189 Note that DSA OpenSSH keys were deprecated in the 4.6 to 4.8 release.
190 If you are upgrading from a release older than 4.8 and use DSA OpenSSH
191 keys, please update your private/public key pair or risk locking
194 AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED
195 -----------------------------------------------
197 They were all in our X86_64_GENERIC kernel configuration file, along with
198 the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom
199 configuration files derived from it need adjustment.
201 PORTAL FILE SYSTEM REMOVED
202 --------------------------
204 It has been broken for a long time now.
206 BINUTILS 2.27 REPLACES 2.24, PRIMARY
207 ------------------------------------
209 The oldest of the two versions of Binutils, version 2.24, was removed
210 and replaced with Binutils 2.27. It becomes the primary version version
211 of binutils and version 2.25 becomes the alternate.
213 The accepted values of BINUTILSVER are now "binutils227" (default) and
214 "binutils225". The building of Binutils 2.25 can be prevented by setting
215 NO_ALTBINUTILS=yes in make.conf.
217 COMPAT_43 KERNEL OPTION REMOVED
218 -------------------------------
220 It was commented out in our default configs for several years now, but
221 might still be present in custom configs created before Nov. 2011.
226 OpenSSL has been removed from base and replaced with a private version of
227 LibreSSL. The previously installed OpenSSL libraries, headers, and man
228 pages will remain on the system unless the "make upgrade" command is
229 specifically instructed to remove them. To do this, define
230 REMOVE_OPENSSL_FILES for the upgrade command, e.g.
231 "make upgrade REMOVE_OPENSSL_FILES=yes"
233 28-Oct-2016: openssl has been replaced by ressl. It is recommended that any
234 stale OpenSSL files be removed to avoid configuration scripts from using
235 the stale and potentially vulnerable version, but all binaries that are
236 dynamically linked to the OpenSSL libraries should be rebuilt first to
242 It has become too cumbersome to maintain HPN patches in OpenSSH in base.
243 To use OpenSSH in base remove HPN config, if you have added it.
244 Check files below for HPN config, see a few lines below.
245 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config
246 sshd(8) will fail to start if HPN config is used.
248 NOTE: HPN config in sshd_config will prohibit remote access to host using ssh.
260 OpenSSH HPN is a patch set to OpenSSH providing higher performance under some
261 circumstances, especially for networking.
262 If HPN functionality is needed, install security/openssh from dports.
264 CS, EX AND VX DRIVERS REMOVED
265 -----------------------------
267 The cs(4), ex(4) and vx(4) drivers have been removed. They were very
268 old and its doubtful they ever worked properly in x86_64 but they were
269 in X86_64_GENERIC, so custom configurations derived from it have to be
272 +-----------------------------------------------------------------------+
273 + UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS +
274 +-----------------------------------------------------------------------+
279 The am-utils automounter suite has been removed. It stopped working
280 at some point and was never fixed. autofs(5) and the associated
281 userland has been brought in from FreeBSD and replaces it.
286 The an(4) driver has been removed. It was in the X86_64_GENERIC kernel
287 config file, so any configurations derived from it have to be adjusted.
289 /DEV/DRI GROUP CHANGED
290 ----------------------
292 The default group assigned to /dev/dri entries has been changed
293 from 'wheel' to 'video' with the id of '44'. If you want to have
294 access to the dri devices please add yourself to the video group
297 # pw groupmod video -m $USER
299 +-----------------------------------------------------------------------+
300 + UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS +
301 +-----------------------------------------------------------------------+
306 dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was
307 in our default kernel config file. So the DSCHED_FQ option has been turned
308 into a no-op for now and can be removed from custom configurations.
310 EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO
311 -------------------------------------------------
313 The est(4) driver has been removed. All CPUs it supported (except one)
314 were 32 bits only. Those who are still using the Core 2 Duo T7500 should
315 report back if there are any issues with this CPU and our regular ACPI
318 Also, compile_et(1) and com_err(3) have been removed as well. They
319 should have been removed along with kerberos support, back in 2009.
321 SEVERAL LOCALES RENAMED
322 -----------------------
324 Several locales were using obsolete and misleading names, and thus have
325 been adjusted to current standards. Any users of the following locales
326 need to select alternates:
328 DFLY 4.2 locale DFLY 4.4 alterative locale

351 BINUTILS 2.25 REPLACES 2.22, PRIMARY
352 ------------------------------------
354 The oldest of the two versions of Binutils, version 2.22, was removed
355 and replaced with Binutils 2.25. It becomes the primary version version
356 of binutils and version 2.24 becomes the alternate. There are 8 current
357 CVE written against 2.24, so for security reasons version 2.25 should
360 The accepted values of BINUTILSVER are now "binutils225" (default) and
361 "binutils224". The building of Binutils 2.24 can be prevented by setting
362 NO_ALTBINUTILS=yes in make.conf.
364 LOADER OPTIONS CHANGED
365 ----------------------
367 Right after the development branch started, the Fred art accompanying the
368 loader menu was improved. The line between Fred and the menu was removed
369 by default (but can optionally be returned) and the placement shifted as
370 a result. The drawing was improved, and the colored version was improved,
371 changing the eyes and wing color from white to red. A new color version
372 of Fred was added, one with a blue scheme.
374 The loader menu defaults have changed since release 4.0: The vertical
375 line was removed, the loader is displayed in color by default*, and the
378 The loader.conf changes are:
379 loader_color: option has been removed
380 loader_plain: option has been added, it changed menu to monochrome
381 fred_is_red: changes color scheme from blue to red
382 fred_is_blue: option existed only on 4.1, it has been removed
383 fred_separated: Adds line between Fred and menu (as seen previously)
385 * If loader.conf defines "console" as "comconsole" or "console" is defined
386 in the environment as "comconsole" then color will not be displayed,
387 even if loader_plain value is "NO".
389 SENDMAIL REMOVED FROM BASE
390 --------------------------
392 The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
393 If the system being upgraded is still configured to use the sendmail
394 binaries from base, the "make upgrade" command will fail.
396 The administrator must change /etc/mail/mailer.conf to switch the
397 mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
398 command that permanently removes sendmail executables and could
399 potentially break a running mail server.
401 Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for
402 detailed instructions on how to configure the MTA selection.
404 _KPOSIX_VERSION and P1003_1B OPTIONS REMOVED
405 --------------------------------------------
407 The _KPOSIX_VERSION and P1003_1B kernel options have been changed to
408 no-ops. They can be removed from custom kernel configurations.
410 SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT
411 --------------------------------------------
413 Many more sound devices may be detected.
415 If the default device chosen isn't to your liking, setting the sysctl
416 hw.snd.default_unit to a different number will change it.
421 Support for the SCTP protocol has been removed.
423 OLD USB DRIVERS REMOVED
424 -----------------------
426 The old USB stack, along with the kernel config option "device oldusb"
427 and the make.conf variable "WANT_OLDUSB" have been removed. This means
428 that for custom kernel configuration files which were derived from a
429 GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
430 various (old USB stack specific) devices will now complain about being
434 * natausb (not yet ported to usb4bsd)
435 * rue (not yet ported to usb4bsd)
436 * ugen (no longer needed in usb4bsd)
437 * urio (not yet ported to usb4bsd)
438 * uscanner (no longer needed in usb4bsd)
440 They should be removed or commented out in such custom kernel configs.
445 The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
446 The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
447 NO_CXX. The latter was never documented and the latest versions of GCC are
448 partially written in C++ so a C++ compiler is no longer optional. In
449 practical terms it has not been optional for many years as other base
450 components are also written in C++. The resource savings by avoiding
451 building Objective-C compiler is so small, the complexity added by NO_OBJC
452 internally was deemed a bad tradeoff so that is the reason for its removal.
453 Also note that no "info" pages are installed with GCC 5. After this entry
454 was originally written, all info pages were removed from DragonFly.
456 GCC 5.1 has been designated as the primary compiler. As such, there is a
457 new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
458 the designated secondary compiler, GCC 4.7. However, while DPorts
459 primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
460 if building ports from source is desired, don't block building of the

464 + UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS +
465 +-----------------------------------------------------------------------+
467 SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN
468 -------------------------------------------
470 DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is
471 the default now (even on single-core systems), both for, like, 21 months.
472 We kept the options around as no-ops as a convenience, to allow people
473 using the same config for the then current release and the then current
474 master. That period is now over, so any configs still having those
475 options have to be adjusted.
477 SYSVIPC SYSCALLS MADE NON-OPTIONAL
478 ----------------------------------
480 The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is
481 now compiled in by default. The options are no-ops for now.
483 DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS
484 --------------------------------------------------------------------
486 The default driver for those controllers is now mrsas(4) due to reports
487 of file system corruption using the mfi(4) driver. The whole issue (and
488 how to deal with potential problems when switching) was explained here:
490 http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html
492 A tunable is provided for letting those controllers still attach via
493 the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page).
495 OLDER NETWORK DRIVERS MOVED TO I386 ONLY
496 ----------------------------------------
498 The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
499 and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
500 removed in kernel configs derived from X86_64_GENERIC.

503 + UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS +
504 +-----------------------------------------------------------------------+
506 UPDATE FROM MOST RECENT 3.6
507 ---------------------------
509 Versions of 3.6 built before June 25th have a bug where installworld might
510 crash during installation of the new initrd. Upgrade to the latest version
511 of 3.6 before updating to 3.8 or later.
513 ATM, IPX, NCP AND NWFS SUPPORT DROPPED
514 --------------------------------------
516 Support for the IPX and NCP network protocols and for mouting NetWare
517 file systems has been dropped. Dito for ATM protocol support.
519 INITRD IMAGES NOW INSTALLED BY DEFAULT
520 --------------------------------------
522 An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz
524 Older images installed under the file name of initrd.img will be removed
525 automatically by the make upgrade process.
527 USB4BSD IS NOW THE DEFAULT USB STACK
528 ------------------------------------
530 To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and
531 replace "device usb" with "device oldusb" in the kernel configuration.
533 MORE ISA SUPPORT DROPPED
534 ------------------------
536 ISA support has been dropped from the following drivers: adv(4), an(4),
537 ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4),
538 si(4), sn(4), and stg(4).
540 +-----------------------------------------------------------------------+
541 + UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS +
542 +-----------------------------------------------------------------------+
547 Installed third-party software (dports) will have to be rebuilt after upgrade,
548 or reinstalled from binary packages.
550 UPDATING FROM 3.4 TO 3.6
551 ------------------------
553 This only applies for this specific upgrade due to locale changes; it is
554 not needed for upgrades after 3.6. Please update in this order:
563 See this mailing list post for details:
564 http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html
566 CYRIX OPTIONS REMOVED
567 ---------------------
569 The following Cyrix related options have been removed: CPU_BTB_EN,
570 CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER,
571 CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT,
572 CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS
574 ISA SUPPORT REMOVED FROM RP(4)
575 ------------------------------
577 ISA support has been removed from the rp(4) driver. It is now PCI only.

581 +-----------------------------------------------------------------------+
583 COMPAT_SUNOS OPTION REMOVED
584 ---------------------------
586 The COMPAT_SUNOS option has been removed. It was meant to provide binary
587 compatibility with SunOS 4.x for the sparc32 port of 4.4BSD.
589 ISA SOUND CARD SUPPORT REMOVED
590 ------------------------------
592 The following modules have been removed (all for ISA sound cards):
593 snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko
598 DragonFly has switched base compilers. GCC 4.7 is now the default
599 compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
600 variable ceases to work now.
602 Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
603 /etc/make.conf to prohibit GCC 4.4 from building. However, using it is
604 highly discouraged. There are a few packages in pkgsrc that do not build
605 with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
606 this time, it is recommended to keep both compilers on the base system.
611 The SMP kernel option has been made a no-op. All kernels now feature SMP
612 support. If you have 'options SMP' in your kernel config, you can as well
615 DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED
616 ---------------------------------------------------------------------------
618 The DEVICE_POLLING kernel option has been made a no-op and it has been
619 replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your
620 kernel config, you need to change it to IFPOLL_ENABLE.
622 Also, the KTR_POLLING kernel option has been removed, so it must be
623 removed from kernel configs that have it.
625 BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED
626 ---------------------------------------------------
628 The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA
629 cards will no longer be detected.
631 The same has been done for Stallion multiport serial controllers. stli(4)
632 has been completely removed (along with the stlload(8) and stlstty(8)
633 utilities) and stl(4) was changed to support only PCI cards. Similarly,
634 ISA support was removed from cy(4) too. All these drivers are i386 only.
636 COMPAT_OLDISA OPTION GONE
637 -------------------------
639 The i386 specific COMPAT_OLDISA kernel option has been removed, since
640 nothing needs it anymore.

644 +-----------------------------------------------------------------------+
646 APIC_IO OPTION REMOVED
647 ----------------------
649 The APIC_IO kernel option is no longer accepted after having been without
650 effect for a while. The hw.ioapic_enable tunable now serves its purpose.
651 If you have 'options APIC_IO' in your kernel config, you'll have to
654 WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED
655 -----------------------------------------
657 The wdog framework is now compiled into our kernels by default, so the
658 options are no longer needed.
663 doscmd(1) has been removed. It was i386 only. The doscmd(1) specific
664 NO_X make.conf option was removed too.
669 GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non-
670 default compiler in base (default is still GCC 4.4).
672 Users who wish to build only GCC 4.4 have to replace NO_GCC41 with
673 NO_GCC47 in /etc/make.conf.
678 A new USB stack (from FreeBSD) has been brought in. The following
679 modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass,
680 usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
683 It is not yet the default. To activate it, WANT_USB4BSD=yes has to
684 be put in make.conf and device "usb4bsd" (quotes needed) has to
685 replace device usb in the kernel config. After that, a full
686 build/install/upgrade cycle is needed.
688 Note that this is experimental and incomplete, but we are interested
689 in hearing about issues with it, of course.
691 ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER
692 ---------------------------------------------
694 ISA adapter support was dropped from the aic(4) driver.
696 +-----------------------------------------------------------------------+
697 + UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS +
698 +-----------------------------------------------------------------------+
700 SEVERAL ISA DRIVERS REMOVED
701 ---------------------------
703 The following ISA only drivers have been removed along with a couple of
704 associated userland tools:
720 tw(4) & xten(1) & xtend(8)
724 Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC
725 config and one (aha(4)) is in our X86_64_GENERIC kernel configuration
728 If buildkernel complains about any of these drivers, just remove them
729 from your kernel configuration.
733 Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted
734 values of BINUTILSVERS are now binutils221 and binutils222 (default).
736 BUILDWORLD/-KERNEL PARALLELIZATION WORK
737 ---------------------------------------
738 Due to changes in the way we build with more than one make job, you
739 will have to update install(1) and mkdir(1) prior to buildworld if you
740 want to build with 'make -j':
742 cd /usr/src/usr.bin/xinstall; make; make install; make clean
743 cd /usr/src/bin/mkdir; make; make install; make clean
747 dma(8) has been upgraded to v0.7 which no longer supports the
748 /etc/dma/virtusertable. Some of its functionality has been replaced
749 with the MASQUERADE keyword and the EMAIL environment variable (see
750 the dma(8) manual page).
752 +-----------------------------------------------------------------------+
753 + UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS +
754 +-----------------------------------------------------------------------+
756 GCC 4.4 & BINUTILS 2.21
757 -----------------------
759 GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
760 been made DragonFly's default Binutils.
762 That means that any settings that set CCVER to 'gcc44' are not needed
763 anymore. Instead, CCVER can be set to 'gcc41' to go back to using
766 It also means that 'binutils221' as a value for BINUTILSVER has no
767 effect anymore. 2.17 has been removed and 'binutils220' is available
770 The NO_GCC44 option has been removed and will not affect the build
771 anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
772 building in a similar fashion.
774 Note that you must do a full buildworld/buildkernel for upgrading.
779 The config file for pkg_radd has moved from /etc/settings.conf to
780 /etc/pkg_radd.conf. Save the contents of settings.conf before upgrading
781 if this is needed. This warning only applies if /etc/settings.conf
782 exists. pkg_radd will continue to work with defaults.
784 +-----------------------------------------------------------------------+
786 + UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD +
787 +-----------------------------------------------------------------------+
792 OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.
793 This shouldn't break any 3rd-party software, but you'll need to recompile your
794 3rd-party software if you want it to link against the new version of OpenSSL.
799 A new loader (dloader) has been added which better handles booting from
800 multiple kernel/module versions.
802 To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
808 make buildkernel KERNCONF=<KERNELNAME>
809 make installkernel KERNCONF=<KERNELNAME>
811 Note that you must installworld and run the 'upgrade' target before
812 installing the new kernel.
817 BIND has been removed from the base system. The ldns and drill tools have
818 been added for basic functionality. Use 'drill' where you would normally
819 use nslookup or dig, or install BIND from pkgsrc. It's available as
820 net/bind95, net/bind96, or net/bind97 as of this writing.
822 This only affects older systems upgrading to 2.8. New 2.8+ installs
823 include BIND as a pkgsrc package.
825 +-----------------------------------------------------------------------+
826 + UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM +
828 +-----------------------------------------------------------------------+
830 Instructions on how to obtain and maintain DragonFly source code using git
831 are in the development(7) manual page.
833 To upgrade a DragonFly system from sources you run the following sequence:
837 make buildkernel KERNCONF=<KERNELNAME>
838 make installkernel KERNCONF=<KERNELNAME>
841 You will also want to run the 'upgrade' target to upgrade your /etc and the
842 rest of your system. The upgrade target is aware of stale files created by
843 older DragonFly installations and should delete them automatically.
847 See the build(7) manual page for further information.
849 Once you've done a full build of the world and kernel you can do incremental
850 upgrades of either by using the 'quickworld' and 'quickkernel' targets
851 instead of 'buildworld' and 'buildkernel'. If you have any problems with
852 the quick targets, try updating your repo first, and then a full buildworld
853 and buildkernel as shown above, before asking for help.
855 +-----------------------------------------------------------------------+
856 + UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 +
857 +-----------------------------------------------------------------------+
859 In 2.1 kernel and modules has moved to boot directory. For most cases
860 this is handled automatically by 'make upgrade'. A few cases needs manual
863 * When installing a kernel without first doing a make buildworld,
864 installworld and upgrade to the same DESTDIR as kernel:
865 make DESTDIR/boot directory and move kernel and modules into this boot
866 directory; also move kernel.old and modules.old.
867 Typical example is vkernel(7), use (no modules used):
871 chflags noschg kernel
872 mv kernel kernel.old boot
873 chflags schg boot/kernel
875 * When using a boot-only partition, /boot/loader.rc needs to be edited:
876 delete occurrences of '/boot/'.
877 These occurrences can normally be deleted in any case, see loader(8).
879 +-----------------------------------------------------------------------+
880 + UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 +
881 +-----------------------------------------------------------------------+
883 In 1.9 major changes to the disk management infrastructure have taken
884 place. make upgrade may not catch all of your disk devices in /dev,
885 so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
886 are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
887 and MAKEDEV no longer exists.
889 The biggest changes in 1.9 are:
891 (1) That whole-slice devices such as da0s1 no longer share the same device
892 id as partition c devices such as da0s1c.
894 (2) The whole-disk device (e.g. da0) is full raw access to the disk,
895 with no snooping or reserved sectors. Consequently you cannot run
896 disklabel on this device. Instead you must run disklabel on a
899 (3) The 'compatibility' partitions now use slice 0 in the device name,
900 so instead of da0a you must specify da0s0a. Also, as per (1) above,
901 accessing the disklabel for the compatibility partitions must be
902 done via slice 0 (da0s0).
904 (4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
905 and CCD now run through the disk management layer and are assigned
906 real disk management devices. VN and CCD in particular do not usually
907 use a MBR and disklabels must be accessed through the compatibility
908 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
909 don't name it 'ccd0s0' in the config file.
911 Generally speaking, you have to get used to running fdisk and disklabel on
912 the correctly specified device names. A lot of the wiggle, such as running
913 disklabel on a partition, has been removed.

916 + UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD +
917 +-----------------------------------------------------------------------+
922 Kerberos IV (eBones) was removed from the tree, please consider moving to
923 Kerberos 5 (Heimdal).
925 > Package Management System
926 ---------------------------
928 Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
929 management system. The necessary tools to build and maintain packages
930 are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
931 directories are in your PATH variable.
933 In order to obtain a reasonably current snapshot of the pkgsrc tree, use
934 the tarball from NetBSD:
936 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
937 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
939 This tree can then be kept up to date with cvs update:
941 cd /usr/pkgsrc; cvs up
943 NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
944 build and install the pkgsrc bootstrap manually:
946 cd /usr/pkgsrc/bootstrap
947 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

953 +-----------------------------------------------------------------------+
955 The compatibility shims for the build environment have been removed, you
956 have to update to DragonFly 1.2 release branch first.
958 The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
959 The existing configuration can be converted using /etc/pam.d/convert.sh.
960 Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
961 the pam_skey.so module was retired, you have to remove it manually from
962 your configuration, when you convert it.
964 > Required user and group IDs when upgrading from either FreeBSD or DragonFly
965 ---------------------
967 The following users may be missing from your password file. Use vipw and
968 add any that are missing:
970 smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin
971 _pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin
973 The following groups may be missing from your group file. Use vi /etc/group
974 and add any that are missing:
981 > Upgrading to DragonFly from FreeBSD
982 ---------------------
984 You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
985 FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
986 FreeBSD. Note that the DragonFly buildworld target does not try to reuse
987 make depend information, it starts from scratch, so no pre-cleaning of the
988 object hierarchy is necessary.
990 # get the CVS repository (it is placed in /home/dcvs, 500MB).
991 # Please use the -h option and a mirror site to pull the
992 # initial repository, but feel free to use the main repository
993 # machine to pull updates.
994 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
995 # install the source from the CVS hierarchy (remove preexisting
996 # FreeBSD src first) (500MB)
999 cvs -R -d /home/dcvs checkout -P src
1001 # build it (500MB used in /usr/obj)
1005 make buildkernel KERNCONF=<KERNELNAME>
1007 Once you have built DragonFly you have to install it over FreeBSD. Since
1008 DragonFly does not track changes made by FreeBSD to its include file
1009 hierarchy and include file pollution can cause all sorts of unexpected
1010 compilation issues to come up, it is best to wipe your include hierarchy
1011 prior to installing DragonFly. Note that you should not wipe any installed
1012 FreeBSD header files or binaries until after you have successfully completed
1013 the build steps above.
1017 make installkernel KERNCONF=<KERNELNAME>
1020 Then you need to upgrade your system. DragonFly's 'make upgrade' target
1021 will unconditionally upgrade the /etc files that sysops do not usually
1022 mess around with, such as the files in /etc/rc.d. It will also remove any
1023 obsolete files such as utilities and manpages that have been removed from
1024 the system since the version you're coming from. If you are unsure we
1025 recommend that you make a backup of at least your /etc before applying
1026 this step. Note that DragonFly's RC system is basically RCNG from
1027 FreeBSD-5, but there are some differences in the contents of the RC files.
1031 NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
1032 Doing so might leave your system in an unusable state.
1034 Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
1035 /usr/bin, and /usr/lib, and remove any stale files that you find. Please
1036 report these files to the DragonFly developers so that they can be added to
1037 the 'upgrade' target.
