13 + UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD +
14 +-----------------------------------------------------------------------+
19 OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.
20 This shouldn't break any 3rd-party software, but you'll need to recompile your
21 3rd-party software if you want it to link against the new version of OpenSSL.
26 A new loader (dloader) has been added which better handles booting from
27 multiple kernel/module versions.
29 To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
35 make buildkernel KERNCONF=<KERNELNAME>
36 make installkernel KERNCONF=<KERNELNAME>
38 Note that you must installworld and run the 'upgrade' target before
39 installing the new kernel.
44 BIND has been removed from the base system. The ldns and drill tools have
45 been added for basic functionality. Use 'drill' where you would normally
46 use nslookup or dig, or install BIND from pkgsrc. It's available as
47 net/bind95, net/bind96, or net/bind97 as of this writing.
49 This only affects older systems upgrading to 2.8. New 2.8+ installs
50 include BIND as a pkgsrc package.

53 + UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM +
55 +-----------------------------------------------------------------------+
57 Instructions on how to obtain and maintain DragonFly source code using git
58 are in the development(7) manual page.
60 To upgrade a DragonFly system from sources you run the following sequence:
64 make buildkernel KERNCONF=<KERNELNAME>
65 make installkernel KERNCONF=<KERNELNAME>
68 You will also want to run the 'upgrade' target to upgrade your /etc and the
69 rest of your system. The upgrade target is aware of stale files created by
70 older DragonFly installations and should delete them automatically.
74 See the build(7) manual page for further information.
76 Once you've done a full build of the world and kernel you can do incremental
77 upgrades of either by using the 'quickworld' and 'quickkernel' targets
78 instead of 'buildworld' and 'buildkernel'. If you have any problems with
79 the quick targets, try updating your repo first, and then a full buildworld
80 and buildkernel as shown above, before asking for help.
82 +-----------------------------------------------------------------------+
83 + UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 +
84 +-----------------------------------------------------------------------+
86 In 2.1 kernel and modules has moved to boot directory. For most cases
87 this is handled automatically by 'make upgrade'. A few cases needs manual
90 * When installing a kernel without first doing a make buildworld,
91 installworld and upgrade to the same DESTDIR as kernel:
92 make DESTDIR/boot directory and move kernel and modules into this boot
93 directory; also move kernel.old and modules.old.
94 Typical example is vkernel(7), use (no modules used):
99 mv kernel kernel.old boot
100 chflags schg boot/kernel
102 * When using a boot-only partition, /boot/loader.rc needs to be edited:
103 delete occurrences of '/boot/'.
104 These occurences can normally be deleted in any case, see loader(8).
106 +-----------------------------------------------------------------------+
107 + UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 +
108 +-----------------------------------------------------------------------+
110 In 1.9 major changes to the disk management infrastructure have taken
111 place. make upgrade may not catch all of your disk devices in /dev,
112 so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
113 are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
114 and MAKEDEV no longer exists.
116 The biggest changes in 1.9 are:
118 (1) That whole-slice devices such as da0s1 no longer share the same device
119 id as partition c devices such as da0s1c.
121 (2) The whole-disk device (e.g. da0) is full raw access to the disk,
122 with no snooping or reserved sectors. Consequently you cannot run
123 disklabel on this device. Instead you must run disklabel on a
126 (3) The 'compatibility' partitions now use slice 0 in the device name,
127 so instead of da0a you must specify da0s0a. Also, as per (1) above,
128 accessing the disklabel for the compatibility partitions must be
129 done via slice 0 (da0s0).
131 (4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
132 and CCD now run through the disk management layer and are assigned
133 real disk management devices. VN and CCD in particular do not usually
134 use a MBR and disklabels must be accessed through the compatibility
135 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
136 don't name it 'ccd0s0' in the config file.
138 Generally speaking, you have to get used to running fdisk and disklabel on
139 the correctly specified device names. A lot of the wiggle, such as running
140 disklabel on a partition, has been removed.

143 + UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD +
144 +-----------------------------------------------------------------------+
149 Kerberos IV (eBones) was removed from the tree, please consider moving to
150 Kerberos 5 (Heimdal).
152 > Package Management System
153 ---------------------------
155 Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
156 management system. The necessary tools to build and maintain packages
157 are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
158 directories are in your PATH variable.
160 In order to obtain a reasonably current snapshot of the pkgsrc tree, use
161 the tarball from NetBSD:
163 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
164 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
166 This tree can then be kept up to date with cvs update:
168 cd /usr/pkgsrc; cvs up
170 NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
171 build and install the pkgsrc bootstrap manually:
173 cd /usr/pkgsrc/bootstrap
174 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

179 + DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) +
180 +-----------------------------------------------------------------------+
182 The compatibility shims for the build environment have been removed, you
183 have to update to DragonFly 1.2 release branch first.
185 The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
186 The existing configuration can be converted using /etc/pam.d/convert.sh.
187 Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
188 the pam_skey.so module was retired, you have to remove it manually from
189 your configuration, when you convert it.
191 > Required user and group IDs when upgrading from either FreeBSD or DragonFly
192 ---------------------
194 The following users may be missing from your password file. Use vipw and
195 add any that are missing:
197 smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin
198 _pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin
200 The following groups may be missing from your group file. Use vi /etc/group
201 and add any that are missing:
208 > Upgrading to DragonFly from FreeBSD
209 ---------------------
211 You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
212 FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
213 FreeBSD. Note that the DragonFly buildworld target does not try to reuse
214 make depend information, it starts from scratch, so no pre-cleaning of the
215 object hierarchy is necessary.
217 # get the CVS repository (it is placed in /home/dcvs, 500MB).
218 # Please use the -h option and a mirror site to pull the
219 # initial repository, but feel free to use the main repository
220 # machine to pull updates.
221 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
222 # install the source from the CVS hierarchy (remove preexisting
223 # FreeBSD src first) (500MB)
226 cvs -R -d /home/dcvs checkout -P src
228 # build it (500MB used in /usr/obj)
232 make buildkernel KERNCONF=<KERNELNAME>
234 Once you have built DragonFly you have to install it over FreeBSD. Since
235 DragonFly does not track changes made by FreeBSD to its include file
236 hierarchy and include file pollution can cause all sorts of unexpected
237 compilation issues to come up, it is best to wipe your include hierarchy
238 prior to installing DragonFly. Note that you should not wipe any installed
239 FreeBSD header files or binaries until after you have successfully completed
240 the build steps above.
244 make installkernel KERNCONF=<KERNELNAME>
247 Then you need to upgrade your system. DragonFly's 'make upgrade' target
248 will unconditionally upgrade the /etc files that sysops do not usually
249 mess around with, such as the files in /etc/rc.d. It will also remove any
250 obsolete files such as utilities and manpages that have been removed from
251 the system since the version you're coming from. If you are unsure we
252 recommend that you make a backup of at least your /etc before applying
253 this step. Note that DragonFly's RC system is basically RCNG from
254 FreeBSD-5, but there are some differences in the contents of the RC files.
258 NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
259 Doing so might leave your system in an unusable state.
261 Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
262 /usr/bin, and /usr/lib, and remove any stale files that you find. Please
263 report these files to the DragonFly developers so that they can be added to
264 the 'upgrade' target.
