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 Once you've done a full build of the world and kernel you can do incremental
59 upgrades of either by using the 'quickworld' and 'quickkernel' targets
60 instead of 'buildworld' and 'buildkernel'. If you have any problems with
61 the quick targets, try doing a cvsup, cvs update, and then a full buildworld
62 and buildkernel as shown above, before asking for help.

65 + UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 +
66 +-----------------------------------------------------------------------+
68 In 1.9 major changes to the disk management infrastructure have taken
69 place. make upgrade may not catch all of your disk devices in /dev,
70 so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
71 are all of your disk devices.
73 The biggest changes in 1.9 are:
75 (1) That whole-slice devices such as da0s1 no longer share the same device
76 id as partition c devices such as da0s1c.
78 (2) The whole-disk device (e.g. da0) is full raw access to the disk,
79 with no snooping or reserved sectors. Consequently you cannot run
80 disklabel on this device. Instead you must run disklabel on a
83 (3) The 'compatibility' partitions now use slice 0 in the device name,
84 so instead of da0a you must specify da0s0a. Also, as per (1) above,
85 accessing the disklabel for the compatibility partitions must be
86 done via slice 0 (da0s0).
88 (4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
89 and CCD now run through the disk management layer and are assigned
90 real disk management devices. VN and CCD in particular do not usually
91 use a MBR and disklabels must be accessed through the compatibility
92 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
93 don't name it 'ccd0s0' in the config file.
95 Generally speaking, you have to get used to running fdisk and disklabel on
96 the correctly specified device names. A lot of the wiggle, such as running
97 disklabel on a partition, has been removed.

101 +-----------------------------------------------------------------------+
106 Kerberos IV (eBones) was removed from the tree, please consider moving to
107 Kerberos 5 (Heimdal).
109 > Package Management System
110 ---------------------------
112 Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
113 management system. The necessary tools to build and maintain packages
114 are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
115 directories are in your PATH variable.
117 In order to obtain a reasonably current snapshot of the pkgsrc tree, use
118 the tarball from NetBSD:
120 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
121 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
123 This tree can then be kept up to date with cvs update:
125 cd /usr/pkgsrc; cvs up
127 NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
128 build and install the pkgsrc bootstrap manually:
130 cd /usr/pkgsrc/bootstrap
131 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

137 +-----------------------------------------------------------------------+
139 The compatibility shims for the build environment have been removed, you
140 have to update to DragonFly 1.2 release branch first.
142 The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
143 The existing configuration can be converted using /etc/pam.d/convert.sh.
144 Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
145 the pam_skey.so module was retired, you have to remove it manually from
146 your configuration, when you convert it.
148 > Required user and group IDs when upgrading from either FreeBSD or DragonFly
149 ---------------------
151 The following users may be missing from your password file. Use vipw and
152 add any that are missing:
154 smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin
155 _pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin
157 The following groups may be missing from your group file. Use vi /etc/group
158 and add any that are missing:
165 > Upgrading to DragonFly from FreeBSD
166 ---------------------
168 You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
169 FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
170 FreeBSD. Note that the DragonFly buildworld target does not try to reuse
171 make depend information, it starts from scratch, so no pre-cleaning of the
172 object hierarchy is necessary.
174 # get the CVS repository (it is placed in /home/dcvs, 500MB).
175 # Please use the -h option and a mirror site to pull the
176 # initial repository, but feel free to use the main repository
177 # machine to pull updates.
178 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
179 # install the source from the CVS hierarchy (remove preexisting
180 # FreeBSD src first) (500MB)
183 cvs -R -d /home/dcvs checkout -P src
185 # build it (500MB used in /usr/obj)
189 make buildkernel KERNCONF=<KERNELNAME>
191 Once you have built DragonFly you have to install it over FreeBSD. Since
192 DragonFly does not track changes made by FreeBSD to its include file
193 hierarchy and include file pollution can cause all sorts of unexpected
194 compilation issues to come up, it is best to wipe your include hierarchy
195 prior to installing DragonFly. Note that you should not wipe any installed
196 FreeBSD header files or binaries until after you have successfully completed
197 the build steps above.
201 make installkernel KERNCONF=<KERNELNAME>
204 Then you need to upgrade your system. DragonFly's 'make upgrade' target
205 will unconditionally upgrade the /etc files that sysops do not usually
206 mess around with, such as the files in /etc/rc.d. It will also remove any
207 obsolete files such as utilities and manpages that have been removed from
208 the system since the version you're coming from. If you are unsure we
209 recommend that you make a backup of at least your /etc before applying
210 this step. Note that DragonFly's RC system is basically RCNG from
211 FreeBSD-5, but there are some differences in the contents of the RC files.
215 NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
216 Doing so might leave your system in an unusable state.
218 Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
219 /usr/bin, and /usr/lib, and remove any stale files that you find. Please
220 report these files to the DragonFly developers so that they can be added to
221 the 'upgrade' target.
