$DragonFly: src/UPDATING,v 1.10 2004/11/23 02:20:40 hmp Exp $ Updating Information for DragonFly users. This file should warn you of any pitfalls which you might need to work around when trying to update your DragonFly system. If you discover any problem, please contact the bugs@lists.dragonflybsd.org mailing list with the details. ------------------------------------------------------------------------------ > Required user and group IDs when upgrading from either FreeBSD or DragonFly --------------------- The following users may be missing from your password file.

Note that the DragonFly buildworld target does not try to reuse make depend information, it starts from scratch, so no pre-cleaning of the object hierarchy is necessary. # get the CVS repository (it is placed in /home/dcvs, 500MB). # Please use the -h option and a mirror site to pull the # initial repository, but feel free to use the main repository # machine to pull updates. cvsup /usr/share/examples/cvsup/DragonFly-supfile # install the source from the CVS hierarchy (remove preexisting # FreeBSD src first) (500MB) cd /usr rm -rf src cvs -R -d /home/dcvs checkout src cvs -R -d /home/dcvs checkout dfports # build it (500MB used in /usr/obj) # cd /usr/src make buildworld make buildkernel KERNCONF= Once you have built DragonFly you have to install it over FreeBSD. Since DragonFly does not track changes made by FreeBSD to its include file hierarchy and include file pollution can cause all sorts of unexpected compilation issues to come up, it is best to wipe your include hierarchy prior to installing DragonFly. Note that you should not wipe any installed FreeBSD header files or binaries until after you have successfully completed the build steps above. rm -rf /usr/include mkdir /usr/include make installkernel KERNCONF= make installworld Then you need to upgrade your /etc. DragonFly's 'make upgrade' target will unconditionally upgrade the /etc files that sysops do not usually mess around with, such as the files in /etc/rc.d. If you are unsure we recommend that you make a backup of your /etc before applying this step. Note that DragonFly's RC system is basically RCNG from FreeBSD-5, but there are some differences in the contents of the RC files. make upgrade Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, /usr/bin, and /usr/lib, and remove any stale files that you find. ------------------------------------------------------------------------------ > Upgrading DragonFly on an existing DragonFly system. --------------------- The best way to upgrade DragonFly is to maintain a copy of the DragonFly CVS repository via cvsup and to checkout the source base and DragonFly ports via this repository. The repository is stored in /home/dcvs by default and requires about 500MB of disk space. The checked out source tree (/usr/src) requires about 500MB of disk space, and the build will eat around 500MB of space out of /usr/obj. To maintain the build you should reserve at least 2GB of disk space, and 3GB if you have the space. Note: most people run cvsup via a root cron job to keep the repository up to date. Please limit such automatic updates to once a day and try to randomize the hour and minute in the cron job a bit to avoid pileups. # get the CVS repository (it is placed in /home/dcvs) cvsup /usr/share/examples/cvsup/DragonFly-supfile # install the source from the CVS hierarchy cd /usr cvs -R -d /home/dcvs checkout src cvs -R -d /home/dcvs checkout dfports Once you have the repository and broken out sources you can decide whether to update your sources from the repository automatically or manually. Since you are tracking changes made to DragonFly, it is usually a good idea to update the sources manually: cd /usr/src cvs update To upgrade a DragonFly system from sources you run the following sequence: cd /usr/src make buildworld make buildkernel KERNCONF= make installkernel KERNCONF= make installworld You will also want to run the 'upgrade' target to upgrade your /etc. The upgrade target is aware of stale files created by older DragonFly installations and should delete them automatically. make upgrade If you are using 'config' manually from /usr/src/sys/i386/conf/BLAH, note that the build will use the current DragonFly environment rather then the post-build environment from the last buildworld. For this reason manual configs are discouraged. The proper way to build a kernel is to use the 'buildkernel' or 'quickkernel' target in /usr/src. Once you've done a full build of the world and kernel you can do incremental upgrades of either by using the 'quickworld' and 'quickkernel' targets instead of 'buildworld' and 'buildkernel'. If you have any problems with the quick targets, try doing a cvsup, cvs update, and then a full buildworld and buildkernel as shown above, before asking for help. > Kerberos IV ------------- Kerberos IV (eBones) was removed from the tree, please consider moving to Kerberos 5 (Heimdal). > FreeBSD and DragonFly ports ----------------------------- DragonFly will eventually have its own package management system but at the moment we leverage off of the FreeBSD ports system. You should maintain /usr/ports from the FreeBSD cvs repository via cvsup just like you do now. DragonFly has its own 'port overrides' hierarchy in /usr/dfports. You can check this out of the DragonFly cvs repository using: cd /usr cvs -R -d /cvs checkout dfports You may wish to use a consolidated distfiles directory, in which case you should make /usr/dfports/distfiles a softlink to your existing distfiles directory (typically /usr/ports/distfiles). Be sure that you have installed 'relpath' from the DragonFly sources (/usr/src/usr.bin/relpath) as well as the updated /usr/share/mk files from /usr/src/share/mk. As a test you can cd into /usr/ports/sysutils/cpdup and build the port. Dragonfly should contain an override and you should see a warning message that the DragonFly override is being build instead when you build it from the FreeBSD ports.
