11 +-----------------------------------------------------------------------+
12 + UPGRADING DRAGONFLY FROM 5.0 TO LATER VERSIONS +
13 +-----------------------------------------------------------------------+
15 BOOTSTRAPPING LIMITED FROM PRE 4.4
16 ----------------------------------
18 Upgrading to 5.1 and later versions now require at least 4.4 in
19 preparations for upcoming base compilers updates.
22 IF_PPP AND PPPD REMOVED
23 -----------------------
25 It has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had
26 already been removed from our default kernel configuration before 5.0,
27 so only people with custom configurations based on earlier X86_64_GENERIC
28 will have to remove it manually.
30 +-----------------------------------------------------------------------+
31 + UPGRADING DRAGONFLY FROM 4.8 TO LATER VERSIONS +
32 +-----------------------------------------------------------------------+
34 FFS_ROOT OPTION DISABLED
35 ------------------------
37 The FFS_ROOT option has been made a no-op and will be completely removed
38 at some point in the future. Users with a custom kernel configuration
39 can remove this option from it now.
41 +-----------------------------------------------------------------------+
42 + UPGRADING DRAGONFLY FROM 4.6 TO LATER VERSIONS +
43 +-----------------------------------------------------------------------+
45 AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED
46 -----------------------------------------------
48 They were all in our X86_64_GENERIC kernel configuration file, along with
49 the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom
50 configuration files derived from it need adjustment.
52 PORTAL FILE SYSTEM REMOVED
53 --------------------------
55 It has been broken for a long time now.
57 BINUTILS 2.27 REPLACES 2.24, PRIMARY
58 ------------------------------------
60 The oldest of the two versions of Binutils, version 2.24, was removed
61 and replaced with Binutils 2.27. It becomes the primary version version
62 of binutils and version 2.25 becomes the alternate.
64 The accepted values of BINUTILSVER are now "binutils227" (default) and
65 "binutils225". The building of Binutils 2.25 can be prevented by setting
66 NO_ALTBINUTILS=yes in make.conf.
68 COMPAT_43 KERNEL OPTION REMOVED
69 -------------------------------
71 It was commented out in our default configs for several years now, but
72 might still be present in custom configs created before Nov. 2011.
74 OPENSSL REMOVED
75 ---------------
77 OpenSSL has been removed from base and replaced with a private version of
78 LibreSSL. The previously installed OpenSSL libraries, headers, and man
79 pages will remain on the system unless the "make upgrade" command is
80 specifically instructed to remove them. To do this, define
81 REMOVE_OPENSSL_FILES for the upgrade command, e.g.
82 "make upgrade REMOVE_OPENSSL_FILES=yes"
84 28-Oct-2016: openssl has been replaced by ressl. It is recommended that any
85 stale OpenSSL files be removed to avoid configuration scripts from using
86 the stale and potentially vulnerable version, but all binaries that are
87 dynamically linked to the OpenSSL libraries should be rebuilt first to
88 avoid breakage.
90 OPENSSH HPN REMOVED
91 -------------------
93 It has become too cumbersome to maintain HPN patches in OpenSSH in base.
94 To use OpenSSH in base remove HPN config, if you have added it.
95 Check files below for HPN config, see a few lines below.
96 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config
97 sshd(8) will fail to start if HPN config is used.
99 NOTE: HPN config in sshd_config will prohibit remote access to host using ssh.
101 HPN config:
102 HPNDisabled
103 HPNBufferSize
104 TcpRcvBuf
105 TcpRcvBufPoll
106 NoneEnabled
107 NoneSwitch
108 cipher MTR-AES-CTR
109 cipher NONE
111 OpenSSH HPN is a patch set to OpenSSH providing higher performance under some
112 circumstances, especially for networking.
113 If HPN functionality is needed, install security/openssh from dports.
115 CS, EX AND VX DRIVERS REMOVED
116 -----------------------------
118 The cs(4), ex(4) and vx(4) drivers have been removed. They were very
119 old and its doubtful they ever worked properly in x86_64 but they were
120 in X86_64_GENERIC, so custom configurations derived from it have to be
121 adjusted.
123 +-----------------------------------------------------------------------+
124 + UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS +
125 +-----------------------------------------------------------------------+
127 AMD REMOVED
128 -----------
130 The am-utils automounter suite has been removed. It stopped working
131 at some point and was never fixed. autofs(5) and the associated
132 userland has been brought in from FreeBSD and replaces it.
134 AN DRIVER REMOVED
135 -----------------
137 The an(4) driver has been removed. It was in the X86_64_GENERIC kernel
138 config file, so any configurations derived from it have to be adjusted.
140 /DEV/DRI GROUP CHANGED
141 ----------------------
143 The default group assigned to /dev/dri entries has been changed
144 from 'wheel' to 'video' with the id of '44'. If you want to have
145 access to the dri devices please add yourself to the video group
146 with:
148 # pw groupmod video -m $USER
150 +-----------------------------------------------------------------------+
151 + UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS +
152 +-----------------------------------------------------------------------+
154 DSCHED REMOVED
155 --------------
157 dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was
158 in our default kernel config file. So the DSCHED_FQ option has been turned
159 into a no-op for now and can be removed from custom configurations.
161 EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO
162 -------------------------------------------------
164 The est(4) driver has been removed. All CPUs it supported (except one)
165 were 32 bits only. Those who are still using the Core 2 Duo T7500 should
166 report back if there are any issues with this CPU and our regular ACPI
167 P-state support.
169 Also, compile_et(1) and com_err(3) have been removed as well. They
170 should have been removed along with kerberos support, back in 2009.
172 SEVERAL LOCALES RENAMED
173 -----------------------
175 Several locales were using obsolete and misleading names, and thus have
176 been adjusted to current standards. Any users of the following locales
177 need to select alternates:
179 DFLY 4.2 locale DFLY 4.4 alterative locale
180 --------------- ------------------------------------
181 mn_MN.UTF-8 mn_Cyrl_MN.UTF-8
182 no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8
183 no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1
184 no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15
185 sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8

198 +-----------------------------------------------------------------------+
199 + UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS +
200 +-----------------------------------------------------------------------+
202 BINUTILS 2.25 REPLACES 2.22, PRIMARY
203 ------------------------------------
205 The oldest of the two versions of Binutils, version 2.22, was removed
206 and replaced with Binutils 2.25. It becomes the primary version version
207 of binutils and version 2.24 becomes the alternate. There are 8 current
208 CVE written against 2.24, so for security reasons version 2.25 should
209 always be used.
211 The accepted values of BINUTILSVER are now "binutils225" (default) and
212 "binutils224". The building of Binutils 2.24 can be prevented by setting
213 NO_ALTBINUTILS=yes in make.conf.
215 LOADER OPTIONS CHANGED
216 ----------------------
218 Right after the development branch started, the Fred art accompanying the
219 loader menu was improved. The line between Fred and the menu was removed
220 by default (but can optionally be returned) and the placement shifted as
221 a result. The drawing was improved, and the colored version was improved,
222 changing the eyes and wing color from white to red. A new color version
223 of Fred was added, one with a blue scheme.
225 The loader menu defaults have changed since release 4.0: The vertical
226 line was removed, the loader is displayed in color by default*, and the
227 blue scheme is used.
229 The loader.conf changes are:
230 loader_color: option has been removed
231 loader_plain: option has been added, it changed menu to monochrome
232 fred_is_red: changes color scheme from blue to red
233 fred_is_blue: option existed only on 4.1, it has been removed
234 fred_separated: Adds line between Fred and menu (as seen previously)
236 * If loader.conf defines "console" as "comconsole" or "console" is defined
237 in the environment as "comconsole" then color will not be displayed,
238 even if loader_plain value is "NO".
240 SENDMAIL REMOVED FROM BASE
241 --------------------------
243 The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
244 If the system being upgraded is still configured to use the sendmail
245 binaries from base, the "make upgrade" command will fail.
247 The administrator must change /etc/mail/mailer.conf to switch the
248 mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
249 command that permanently removes sendmail executables and could
250 potentially break a running mail server.
252 Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for
253 detailed instructions on how to configure the MTA selection.
255 _KPOSIX_VERSION and P1003_1B OPTIONS REMOVED
256 --------------------------------------------
258 The _KPOSIX_VERSION and P1003_1B kernel options have been changed to
259 no-ops. They can be removed from custom kernel configurations.
261 SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT
262 --------------------------------------------
264 Many more sound devices may be detected.
266 If the default device choosen isn't to your liking, setting the sysctl
267 hw.snd.default_unit to a different number will change it.
269 SCTP SUPPORT DROPPED
270 --------------------
272 Support for the SCTP protocol has been removed.
274 OLD USB DRIVERS REMOVED
275 -----------------------
277 The old USB stack, along with the kernel config option "device oldusb"
278 and the make.conf variable "WANT_OLDUSB" have been removed. This means
279 that for custom kernel configuration files which were derived from a
280 GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
281 various (old USB stack specific) devices will now complain about being
282 unknown:
284 * oldusb (obviously)
285 * natausb (not yet ported to usb4bsd)
286 * rue (not yet ported to usb4bsd)
287 * ugen (no longer needed in usb4bsd)
288 * urio (not yet ported to usb4bsd)
289 * uscanner (no longer needed in usb4bsd)
291 They should be removed or commented out in such custom kernel configs.
293 GCC 5
294 -----
296 The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
297 The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
298 NO_CXX. The latter was never documented and the latest versions of GCC are
299 partially written in C++ so a C++ compiler is no longer optional. In
300 practical terms it has not been optional for many years as other base
301 components are also written in C++. The resource savings by avoiding
302 building Objective-C compiler is so small, the complexity added by NO_OBJC
303 internally was deemed a bad tradeoff so that is the reason for its removal.
304 Also note that no "info" pages are installed with GCC 5. After this entry
305 was originally written, all info pages were removed from DragonFly.
307 GCC 5.1 has been designated as the primary compiler. As such, there is a
308 new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
309 the designated secondary compiler, GCC 4.7. However, while DPorts
310 primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
311 if building ports from source is desired, don't block building of the
312 secondary compiler.
314 +-----------------------------------------------------------------------+
315 + UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS +
316 +-----------------------------------------------------------------------+
318 SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN
319 -------------------------------------------
321 DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is
322 the default now (even on single-core systems), both for, like, 21 months.
323 We kept the options around as no-ops as a convenience, to allow people
324 using the same config for the then current release and the then current
325 master. That period is now over, so any configs still having those
326 options have to be adjusted.
328 SYSVIPC SYSCALLS MADE NON-OPTIONAL
329 ----------------------------------
331 The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is
332 now compiled in by default. The options are no-ops for now.
334 DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS
335 --------------------------------------------------------------------
337 The default driver for those controllers is now mrsas(4) due to reports
338 of file system corruption using the mfi(4) driver. The whole issue (and
339 how to deal with potential problems when switching) was explained here:
341 http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html
343 A tunable is provided for letting those controllers still attach via
344 the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page).
346 OLDER NETWORK DRIVERS MOVED TO I386 ONLY
347 ----------------------------------------
349 The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
350 and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
351 removed in kernel configs derived from X86_64_GENERIC.
353 +-----------------------------------------------------------------------+
354 + UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS +
355 +-----------------------------------------------------------------------+
357 UPDATE FROM MOST RECENT 3.6
358 ---------------------------
360 Versions of 3.6 built before June 25th have a bug where installworld might
361 crash during installation of the new initrd. Upgrade to the latest version
362 of 3.6 before updating to 3.8 or later.
364 ATM, IPX, NCP AND NWFS SUPPORT DROPPED
365 --------------------------------------
367 Support for the IPX and NCP network protocols and for mouting NetWare
368 file systems has been dropped. Dito for ATM protocol support.
370 INITRD IMAGES NOW INSTALLED BY DEFAULT
371 --------------------------------------
373 An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz
375 Older images installed under the file name of initrd.img will be removed
376 automatically by the make upgrade process.
378 USB4BSD IS NOW THE DEFAULT USB STACK
379 ------------------------------------
381 To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and
382 replace "device usb" with "device oldusb" in the kernel configuration.
384 MORE ISA SUPPORT DROPPED
385 ------------------------
387 ISA support has been dropped from the following drivers: adv(4), an(4),
388 ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4),
389 si(4), sn(4), and stg(4).
391 +-----------------------------------------------------------------------+
392 + UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS +
393 +-----------------------------------------------------------------------+
395 ABI CHANGE
396 ----------
398 Installed third-party software (dports) will have to be rebuilt after upgrade,
399 or reinstalled from binary packages.
401 UPDATING FROM 3.4 TO 3.6
402 ------------------------
404 This only applies for this specific upgrade due to locale changes; it is
405 not needed for upgrades after 3.6. Please update in this order:
407 make buildworld
408 make buildkernel
409 make installworld
410 make installkernel
411 *reboot*
412 make upgrade
414 See this mailing list post for details:
415 http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html
417 CYRIX OPTIONS REMOVED
418 ---------------------
420 The following Cyrix related options have been removed: CPU_BTB_EN,
421 CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER,
422 CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT,
423 CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS
425 ISA SUPPORT REMOVED FROM RP(4)
426 ------------------------------
428 ISA support has been removed from the rp(4) driver. It is now PCI only.
430 +-----------------------------------------------------------------------+
431 + UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS +
432 +-----------------------------------------------------------------------+
434 COMPAT_SUNOS OPTION REMOVED
435 ---------------------------
437 The COMPAT_SUNOS option has been removed. It was meant to provide binary
438 compatibility with SunOS 4.x for the sparc32 port of 4.4BSD.
440 ISA SOUND CARD SUPPORT REMOVED
441 ------------------------------
443 The following modules have been removed (all for ISA sound cards):
444 snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko
446 GCC 4.7
447 -------
449 DragonFly has switched base compilers. GCC 4.7 is now the default
450 compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
451 variable ceases to work now.
453 Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
454 /etc/make.conf to prohibit GCC 4.4 from building. However, using it is
455 highly discouraged. There are a few packages in pkgsrc that do not build
456 with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
457 this time, it is recommended to keep both compilers on the base system.
459 SMP OPTION REMOVED
460 ------------------
462 The SMP kernel option has been made a no-op. All kernels now feature SMP
463 support. If you have 'options SMP' in your kernel config, you can as well
464 remove it.
466 DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED
467 ---------------------------------------------------------------------------
469 The DEVICE_POLLING kernel option has been made a no-op and it has been
470 replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your
471 kernel config, you need to change it to IFPOLL_ENABLE.
473 Also, the KTR_POLLING kernel option has been removed, so it must be
474 removed from kernel configs that have it.
476 BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED
477 ---------------------------------------------------
479 The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA
480 cards will no longer be detected.
482 The same has been done for Stallion multiport serial controllers. stli(4)
483 has been completely removed (along with the stlload(8) and stlstty(8)
484 utilities) and stl(4) was changed to support only PCI cards. Similarly,
485 ISA support was removed from cy(4) too. All these drivers are i386 only.
487 COMPAT_OLDISA OPTION GONE
488 -------------------------
490 The i386 specific COMPAT_OLDISA kernel option has been removed, since
491 nothing needs it anymore.
493 +-----------------------------------------------------------------------+
494 + UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS +
495 +-----------------------------------------------------------------------+
497 APIC_IO OPTION REMOVED
498 ----------------------
500 The APIC_IO kernel option is no longer accepted after having been without
501 effect for a while. The hw.ioapic_enable tunable now serves its purpose.
502 If you have 'options APIC_IO' in your kernel config, you'll have to
503 remove it.
505 WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED
506 -----------------------------------------
508 The wdog framework is now compiled into our kernels by default, so the
509 options are no longer needed.
511 DOSCMD(1) REMOVED
512 -----------------
514 doscmd(1) has been removed. It was i386 only. The doscmd(1) specific
515 NO_X make.conf option was removed too.
517 GCC 4.7
518 -------
520 GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non-
521 default compiler in base (default is still GCC 4.4).
523 Users who wish to build only GCC 4.4 have to replace NO_GCC41 with
524 NO_GCC47 in /etc/make.conf.
526 USB4BSD
527 -------
529 A new USB stack (from FreeBSD) has been brought in. The following
530 modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass,
531 usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
532 and uaudio.
534 It is not yet the default. To activate it, WANT_USB4BSD=yes has to
535 be put in make.conf and device "usb4bsd" (quotes needed) has to
536 replace device usb in the kernel config. After that, a full
537 build/install/upgrade cycle is needed.
539 Note that this is experimental and incomplete, but we are interested
540 in hearing about issues with it, of course.
542 ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER
543 ---------------------------------------------
545 ISA adapter support was dropped from the aic(4) driver.
547 +-----------------------------------------------------------------------+
548 + UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS +
549 +-----------------------------------------------------------------------+
551 SEVERAL ISA DRIVERS REMOVED
552 ---------------------------
554 The following ISA only drivers have been removed along with a couple of
555 associated userland tools:
557 aha(4)
558 asc(4) & sasc(1)
559 ctx
560 dgb(4)
561 el(4)
562 gpib
563 gsc(4) & sgsc(1)
564 ie(4)
565 labpc(4)
566 le(4)
567 mse(4)
568 rc(4)
569 rdp(4)
570 spigot
571 tw(4) & xten(1) & xtend(8)
572 wl(4) & wlconfig(8)
573 wt(4)
575 Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC
576 config and one (aha(4)) is in our X86_64_GENERIC kernel configuration
577 file.
579 If buildkernel complains about any of these drivers, just remove them
580 from your kernel configuration.
582 BINUTILS 2.20
583 -------------
584 Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted
585 values of BINUTILSVERS are now binutils221 and binutils222 (default).
587 BUILDWORLD/-KERNEL PARALLELIZATION WORK
588 ---------------------------------------
589 Due to changes in the way we build with more than one make job, you
590 will have to update install(1) and mkdir(1) prior to buildworld if you
591 want to build with 'make -j':
593 cd /usr/src/usr.bin/xinstall; make; make install; make clean
594 cd /usr/src/bin/mkdir; make; make install; make clean
596 DMA(8) UPGRADE
597 --------------
598 dma(8) has been upgraded to v0.7 which no longer supports the
599 /etc/dma/virtusertable. Some of its functionality has been replaced
600 with the MASQUERADE keyword and the EMAIL environment variable (see
601 the dma(8) manual page).
603 +-----------------------------------------------------------------------+
604 + UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS +
605 +-----------------------------------------------------------------------+
607 GCC 4.4 & BINUTILS 2.21
608 -----------------------
610 GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
611 been made DragonFly's default Binutils.
613 That means that any settings that set CCVER to 'gcc44' are not needed
614 anymore. Instead, CCVER can be set to 'gcc41' to go back to using
615 GCC 4.1.
617 It also means that 'binutils221' as a value for BINUTILSVER has no
618 effect anymore. 2.17 has been removed and 'binutils220' is available
619 as an option.
621 The NO_GCC44 option has been removed and will not affect the build
622 anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
623 building in a similar fashion.
625 Note that you must do a full buildworld/buildkernel for upgrading.
627 pkg_radd settings
628 -----------------
630 The config file for pkg_radd has moved from /etc/settings.conf to
631 /etc/pkg_radd.conf. Save the contents of settings.conf before upgrading
632 if this is needed. This warning only applies if /etc/settings.conf
633 exists. pkg_radd will continue to work with defaults.

637 + UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD +
638 +-----------------------------------------------------------------------+
640 OpenSSL
641 --------
643 OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.
644 This shouldn't break any 3rd-party software, but you'll need to recompile your
645 3rd-party software if you want it to link against the new version of OpenSSL.
647 Loader
648 -------
650 A new loader (dloader) has been added which better handles booting from
651 multiple kernel/module versions.
653 To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
655 cd /usr/src
656 make buildworld
657 make installworld
658 make upgrade
659 make buildkernel KERNCONF=<KERNELNAME>
660 make installkernel KERNCONF=<KERNELNAME>
662 Note that you must installworld and run the 'upgrade' target before
663 installing the new kernel.
665 BIND
666 -----
668 BIND has been removed from the base system. The ldns and drill tools have
669 been added for basic functionality. Use 'drill' where you would normally
670 use nslookup or dig, or install BIND from pkgsrc. It's available as
671 net/bind95, net/bind96, or net/bind97 as of this writing.
673 This only affects older systems upgrading to 2.8. New 2.8+ installs
674 include BIND as a pkgsrc package.
676 +-----------------------------------------------------------------------+
677 + UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM +
678 + GENERAL +
679 +-----------------------------------------------------------------------+
681 Instructions on how to obtain and maintain DragonFly source code using git
682 are in the development(7) manual page.
684 To upgrade a DragonFly system from sources you run the following sequence:
686 cd /usr/src
687 make buildworld
688 make buildkernel KERNCONF=<KERNELNAME>
689 make installkernel KERNCONF=<KERNELNAME>
690 make installworld
692 You will also want to run the 'upgrade' target to upgrade your /etc and the
693 rest of your system. The upgrade target is aware of stale files created by
694 older DragonFly installations and should delete them automatically.
696 make upgrade
698 See the build(7) manual page for further information.
700 Once you've done a full build of the world and kernel you can do incremental
701 upgrades of either by using the 'quickworld' and 'quickkernel' targets
702 instead of 'buildworld' and 'buildkernel'. If you have any problems with
703 the quick targets, try updating your repo first, and then a full buildworld
704 and buildkernel as shown above, before asking for help.
706 +-----------------------------------------------------------------------+
707 + UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 +
708 +-----------------------------------------------------------------------+
710 In 2.1 kernel and modules has moved to boot directory. For most cases
711 this is handled automatically by 'make upgrade'. A few cases needs manual
712 intervention:
714 * When installing a kernel without first doing a make buildworld,
715 installworld and upgrade to the same DESTDIR as kernel:
716 make DESTDIR/boot directory and move kernel and modules into this boot
717 directory; also move kernel.old and modules.old.
718 Typical example is vkernel(7), use (no modules used):
720 cd /var/vkernel
721 mkdir boot
722 chflags noschg kernel
723 mv kernel kernel.old boot
724 chflags schg boot/kernel
726 * When using a boot-only partition, /boot/loader.rc needs to be edited:
727 delete occurrences of '/boot/'.
728 These occurences can normally be deleted in any case, see loader(8).
730 +-----------------------------------------------------------------------+
731 + UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 +
732 +-----------------------------------------------------------------------+
734 In 1.9 major changes to the disk management infrastructure have taken
735 place. make upgrade may not catch all of your disk devices in /dev,
736 so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
737 are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
738 and MAKEDEV no longer exists.
740 The biggest changes in 1.9 are:
742 (1) That whole-slice devices such as da0s1 no longer share the same device
743 id as partition c devices such as da0s1c.
745 (2) The whole-disk device (e.g. da0) is full raw access to the disk,
746 with no snooping or reserved sectors. Consequently you cannot run
747 disklabel on this device. Instead you must run disklabel on a
748 whole-slice device.
750 (3) The 'compatibility' partitions now use slice 0 in the device name,
751 so instead of da0a you must specify da0s0a. Also, as per (1) above,
752 accessing the disklabel for the compatibility partitions must be
753 done via slice 0 (da0s0).
755 (4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
756 and CCD now run through the disk management layer and are assigned
757 real disk management devices. VN and CCD in particular do not usually
758 use a MBR and disklabels must be accessed through the compatibility
759 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
760 don't name it 'ccd0s0' in the config file.
762 Generally speaking, you have to get used to running fdisk and disklabel on
763 the correctly specified device names. A lot of the wiggle, such as running
764 disklabel on a partition, has been removed.

770 > Kerberos IV
771 -------------
773 Kerberos IV (eBones) was removed from the tree, please consider moving to
774 Kerberos 5 (Heimdal).
776 > Package Management System
777 ---------------------------
779 Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
780 management system. The necessary tools to build and maintain packages
781 are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
782 directories are in your PATH variable.
784 In order to obtain a reasonably current snapshot of the pkgsrc tree, use
785 the tarball from NetBSD:
787 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
788 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
790 This tree can then be kept up to date with cvs update:
792 cd /usr/pkgsrc; cvs up
794 NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
795 build and install the pkgsrc bootstrap manually:
797 cd /usr/pkgsrc/bootstrap
798 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

803 + DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) +
804 +-----------------------------------------------------------------------+
806 The compatibility shims for the build environment have been removed, you
807 have to update to DragonFly 1.2 release branch first.
809 The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
810 The existing configuration can be converted using /etc/pam.d/convert.sh.
811 Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
812 the pam_skey.so module was retired, you have to remove it manually from
813 your configuration, when you convert it.
815 > Required user and group IDs when upgrading from either FreeBSD or DragonFly
816 ---------------------
818 The following users may be missing from your password file. Use vipw and
819 add any that are missing:
821 smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin
822 _pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin
824 The following groups may be missing from your group file. Use vi /etc/group
825 and add any that are missing:
827 smmsp:*:25:
828 authpf:*:63:
829 _pflogd:*:64:
832 > Upgrading to DragonFly from FreeBSD
833 ---------------------
835 You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
836 FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
837 FreeBSD. Note that the DragonFly buildworld target does not try to reuse
838 make depend information, it starts from scratch, so no pre-cleaning of the
839 object hierarchy is necessary.
841 # get the CVS repository (it is placed in /home/dcvs, 500MB).
842 # Please use the -h option and a mirror site to pull the
843 # initial repository, but feel free to use the main repository
844 # machine to pull updates.
845 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
846 # install the source from the CVS hierarchy (remove preexisting
847 # FreeBSD src first) (500MB)
848 cd /usr
849 rm -rf src
850 cvs -R -d /home/dcvs checkout -P src
852 # build it (500MB used in /usr/obj)
853 #
854 cd /usr/src
855 make buildworld
856 make buildkernel KERNCONF=<KERNELNAME>
858 Once you have built DragonFly you have to install it over FreeBSD. Since
859 DragonFly does not track changes made by FreeBSD to its include file
860 hierarchy and include file pollution can cause all sorts of unexpected
861 compilation issues to come up, it is best to wipe your include hierarchy
862 prior to installing DragonFly. Note that you should not wipe any installed
863 FreeBSD header files or binaries until after you have successfully completed
864 the build steps above.
866 rm -rf /usr/include
867 mkdir /usr/include
868 make installkernel KERNCONF=<KERNELNAME>
869 make installworld
871 Then you need to upgrade your system. DragonFly's 'make upgrade' target
872 will unconditionally upgrade the /etc files that sysops do not usually
873 mess around with, such as the files in /etc/rc.d. It will also remove any
874 obsolete files such as utilities and manpages that have been removed from
875 the system since the version you're coming from. If you are unsure we
876 recommend that you make a backup of at least your /etc before applying
877 this step. Note that DragonFly's RC system is basically RCNG from
878 FreeBSD-5, but there are some differences in the contents of the RC files.
880 make upgrade
882 NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
883 Doing so might leave your system in an unusable state.
885 Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
886 /usr/bin, and /usr/lib, and remove any stale files that you find. Please
887 report these files to the DragonFly developers so that they can be added to
888 the 'upgrade' target.
