14 + UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM +
16 +-----------------------------------------------------------------------+
18 The best way to upgrade DragonFly is to maintain a copy of the DragonFly
19 CVS repository via cvsup and to checkout the source base via this repository.
20 The repository is stored in /home/dcvs by default and requires about 800MB
21 of disk space. The checked out source tree (/usr/src) requires about 400MB
22 of disk space, and the build will eat around 800MB of space out of /usr/obj.
23 To maintain the build you should reserve at least 2.5GB of disk space, and
24 3.5GB if you have the space.
26 Note: most people run cvsup via a root cron job to keep the repository up to
27 date. Please limit such automatic updates to once a day and try to randomize
28 the hour and minute in the cron job a bit to avoid pileups.
30 # get the CVS repository (it is placed in /home/dcvs)
31 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
32 # install the source from the CVS hierarchy
34 cvs -R -d /home/dcvs checkout -P src
36 Once you have the repository and broken out sources you can decide whether to
37 update your sources from the repository automatically or manually. Since
38 you are tracking changes made to DragonFly, it is usually a good idea to
39 update the sources manually:
44 To upgrade a DragonFly system from sources you run the following sequence:
48 make buildkernel KERNCONF=<KERNELNAME>
49 make installkernel KERNCONF=<KERNELNAME>
52 You will also want to run the 'upgrade' target to upgrade your /etc and the
53 rest of your system. The upgrade target is aware of stale files created by
54 older DragonFly installations and should delete them automatically.
58 NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
59 Doing so might leave your system in an unusable state.
61 Once you've done a full build of the world and kernel you can do incremental
62 upgrades of either by using the 'quickworld' and 'quickkernel' targets
63 instead of 'buildworld' and 'buildkernel'. If you have any problems with
64 the quick targets, try doing a cvsup, cvs update, and then a full buildworld
65 and buildkernel as shown above, before asking for help.

68 + UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 +
69 +-----------------------------------------------------------------------+
71 In 1.9 major changes to the disk management infrastructure have taken
72 place. make upgrade may not catch all of your disk devices in /dev,
73 so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
74 are all of your disk devices.
76 The biggest changes in 1.9 are:
78 (1) That whole-slice devices such as da0s1 no longer share the same device
79 id as partition c devices such as da0s1c.
81 (2) The whole-disk device (e.g. da0) is full raw access to the disk,
82 with no snooping or reserved sectors. Consequently you cannot run
83 disklabel on this device. Instead you must run disklabel on a
86 (3) The 'compatibility' partitions now use slice 0 in the device name,
87 so instead of da0a you must specify da0s0a. Also, as per (1) above,
88 accessing the disklabel for the compatibility partitions must be
89 done via slice 0 (da0s0).
91 (4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
92 and CCD now run through the disk management layer and are assigned
93 real disk management devices. VN and CCD in particular do not usually
94 use a MBR and disklabels must be accessed through the compatibility
95 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
96 don't name it 'ccd0s0' in the config file.
98 Generally speaking, you have to get used to running fdisk and disklabel on
99 the correctly specified device names. A lot of the wiggle, such as running
100 disklabel on a partition, has been removed.

109 Kerberos IV (eBones) was removed from the tree, please consider moving to
110 Kerberos 5 (Heimdal).
112 > Package Management System
113 ---------------------------
115 Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
116 management system. The necessary tools to build and maintain packages
117 are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
118 directories are in your PATH variable.
120 In order to obtain a reasonably current snapshot of the pkgsrc tree, use
121 the tarball from NetBSD:
123 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
124 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
126 This tree can then be kept up to date with cvs update:
128 cd /usr/pkgsrc; cvs up
130 NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
131 build and install the pkgsrc bootstrap manually:
133 cd /usr/pkgsrc/bootstrap
134 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

140 +-----------------------------------------------------------------------+
142 The compatibility shims for the build environment have been removed, you
143 have to update to DragonFly 1.2 release branch first.
145 The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
146 The existing configuration can be converted using /etc/pam.d/convert.sh.
147 Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
148 the pam_skey.so module was retired, you have to remove it manually from
149 your configuration, when you convert it.
151 > Required user and group IDs when upgrading from either FreeBSD or DragonFly
152 ---------------------
154 The following users may be missing from your password file. Use vipw and
155 add any that are missing:
157 smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin
158 _pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin
159 _ntp:*:65:65::0:0:ntpd privsep user:/var/empty:/sbin/nologin
161 The following groups may be missing from your group file. Use vi /etc/group
162 and add any that are missing:
170 > Upgrading to DragonFly from FreeBSD
171 ---------------------
173 You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
174 FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
175 FreeBSD. Note that the DragonFly buildworld target does not try to reuse
176 make depend information, it starts from scratch, so no pre-cleaning of the
177 object hierarchy is necessary.
179 # get the CVS repository (it is placed in /home/dcvs, 500MB).
180 # Please use the -h option and a mirror site to pull the
181 # initial repository, but feel free to use the main repository
182 # machine to pull updates.
183 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
184 # install the source from the CVS hierarchy (remove preexisting
185 # FreeBSD src first) (500MB)
188 cvs -R -d /home/dcvs checkout -P src
190 # build it (500MB used in /usr/obj)
194 make buildkernel KERNCONF=<KERNELNAME>
196 Once you have built DragonFly you have to install it over FreeBSD. Since
197 DragonFly does not track changes made by FreeBSD to its include file
198 hierarchy and include file pollution can cause all sorts of unexpected
199 compilation issues to come up, it is best to wipe your include hierarchy
200 prior to installing DragonFly. Note that you should not wipe any installed
201 FreeBSD header files or binaries until after you have successfully completed
202 the build steps above.
206 make installkernel KERNCONF=<KERNELNAME>
209 Then you need to upgrade your system. DragonFly's 'make upgrade' target
210 will unconditionally upgrade the /etc files that sysops do not usually
211 mess around with, such as the files in /etc/rc.d. It will also remove any
212 obsolete files such as utilities and manpages that have been removed from
213 the system since the version you're coming from. If you are unsure we
214 recommend that you make a backup of at least your /etc before applying
215 this step. Note that DragonFly's RC system is basically RCNG from
216 FreeBSD-5, but there are some differences in the contents of the RC files.
220 NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
221 Doing so might leave your system in an unusable state.
223 Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
224 /usr/bin, and /usr/lib, and remove any stale files that you find. Please
225 report these files to the DragonFly developers so that they can be added to
226 the 'upgrade' target.
