| 13 | > Upgrading to DragonFly from FreeBSD |
| 14 | --------------------- |
| 15 | |
| 16 | You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or |
| 17 | FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing |
| 18 | FreeBSD. Note that the DragonFly buildworld target does not try to reuse |
| 19 | make depend information, it starts from scratch, so no pre-cleaning of the |
| 20 | object hierarchy is necessary. |
| 21 | |
| 22 | # get the CVS pository (it is placed in /home/dcvs, 500MB). |
| 23 | # Please use the -h option and a mirror site to pull the |
| 24 | # initial repository, but feel free to use the main repository |
| 25 | # machine to pull updates. |
| 26 | cvsup /usr/share/examples/cvsup/DragonFly-supfile |
| 27 | # install the source from the CVS hierarchy (remove preexisting |
| 28 | # FreeBSD src first) (500MB) |
| 29 | cd /usr |
| 30 | rm -rf src |
| 31 | cvs -R -d /home/dcvs checkout src |
| 32 | cvs -R -d /home/dcvs checkout dfports |
| 33 | |
| 34 | # build it (500MB used in /usr/obj) |
| 35 | # |
| 36 | cd /usr/src |
| 37 | make buildworld |
| 38 | make buildkernel KERNCONF=<KERNELNAME> |
| 39 | |
| 40 | Once you have built DragonFly you have to install it over FreeBSD. Since |
| 41 | DragonFly does not track changes made by FreeBSD to its include file |
| 42 | hierarchy and include file pollution can cause all sorts of unexpected |
| 43 | compilation issues to come up, it is best to wipe your include hierarchy |
| 44 | prior to installing DragonFly. Note that you should not wipe any installed |
| 45 | FreeBSD header files or binaries until after you have successfully completed |
| 46 | the build steps above. |
| 47 | |
| 48 | rm -rf /usr/include |
| 49 | mkdir /usr/include |
| 50 | make installkernel KERNCONF=<KERNELNAME> |
| 51 | make installworld |
| 52 | |
| 53 | Then you need to upgrade your /etc. DragonFly's 'make upgrade' target |
| 54 | will unconditionally upgrade the /etc files that sysops do not usually |
| 55 | mess around with, such as the files in /etc/rc.d. If you are unsure we |
| 56 | recommend that you make a backup of your /etc before applying this step. |
| 57 | Note that DragonFly's RC system is basically RCNG from FreeBSD-5, but |
| 58 | there are some differences in the contents of the RC files. |
| 59 | |
| 60 | make upgrade |
| 61 | |
| 62 | Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, |
| 63 | /usr/bin, and /usr/lib, and remove any stale files that you find. |
| 64 | |

| 66 | |
| 67 | > Upgrading DragonFly on an existing DragonFly system. |
| 68 | --------------------- |
| 69 | |
| 70 | The best way to upgrade DragonFly is to maintain a copy of the DragonFly |
| 71 | CVS repository via cvsup and to checkout the source base and DragonFly |
| 72 | ports via this repository. The repository is stored in /home/dcvs by |
| 73 | default and requires about 500MB of disk space. The checked out source |
| 74 | tree (/usr/src) requires about 500MB of disk space, and the build will |
| 75 | eat around 500MB of space out of /usr/obj. To maintain the build you |
| 76 | should reserve at least 2GB of disk space, and 3GB if you have the space. |
| 77 | |
| 78 | Note: most people run cvsup via a root cron job to keep the repository up to |
| 79 | date. Please limit such automatic updates to once a day and try to randomize |
| 80 | the hour and minute in the cron job a bit to avoid pileups. |
| 81 | |
| 82 | # get the CVS pository (it is placed in /home/dcvs) |
| 83 | cvsup /usr/share/examples/cvsup/DragonFly-supfile |
| 84 | # install the source from the CVS hierarchy |
| 85 | cd /usr |
| 86 | cvs -R -d /home/dcvs checkout src |
| 87 | cvs -R -d /home/dcvs checkout dfports |
| 88 | |
| 89 | Once you have the repository and broken out sources you can decide whether to |
| 90 | update your sources from the repository automatically or manually. Since |
| 91 | you are tracking changes made to DragonFly, it is usually a good idea to |
| 92 | update the sources manually: |
| 93 | |
| 94 | cd /usr/src |
| 95 | cvs update |
| 96 | |
| 97 | To upgrade a DragonFly system from sources you run the following sequence: |
| 98 | |
| 99 | cd /usr/src |
| 100 | make buildworld |
| 101 | make buildkernel KERNCONF=<KERNELNAME> |
| 102 | make installkernel KERNCONF=<KERNELNAME> |
| 103 | make installworld |
| 104 | |
| 105 | You will also want to run the 'upgrade' target to upgrade your /etc. The |
| 106 | upgrade target is aware of stale files created by older DragonFly |
| 107 | installations and should delete them automatically. |
| 108 | |
| 109 | make upgrade |
| 110 | |
| 111 | If you are using 'config' manually from /usr/src/sys/i386/conf/BLAH, note |
| 112 | that the build will use the current DragonFly environment rather then |
| 113 | the post-build environment from the last buildworld. For this reason manual |
| 114 | configs are discouraged. The proper way to build a kernel is to use the |
| 115 | 'buildkernel' or 'quickkernel' target in /usr/src. |
| 116 | |
| 117 | Once you've done a full build of the world and kernel you can do incremental |
| 118 | upgrades of either by using the 'quickworld' and 'quickkernel' targets |
| 119 | instead of 'buildworld' and 'buildkernel'. If you have any problems with |
| 120 | the quick targets, try doing a cvsup, cvs update, and then a full buildworld |
| 121 | and buildkernel as shown above, before asking for help. |
| 122 | |
| 123 | > Kerberos IV |
| 124 | ------------- |
| 125 | |
| 126 | Kerberos IV (eBones) was removed from the tree, please consider moving to |
| 127 | Kerberos 5 (Heimdal). |
| 128 | |
| 129 | > FreeBSD and DragonFly ports |
| 130 | ----------------------------- |
| 131 | |
| 132 | DragonFly will eventually have its own package management system but at the |
| 133 | moment we leverage off of the FreeBSD ports system. You should maintain |
| 134 | /usr/ports from the FreeBSD cvs repository via cvsup just like you do now. |
| 135 | |
| 136 | DragonFly has its own 'port overrides' hierarchy in /usr/dfports. You can |
| 137 | check this out of the DragonFly cvs repository using: |
| 138 | |
| 139 | cd /usr |
| 140 | cvs -R -d /cvs checkout dfports |
| 141 | |
| 142 | You may wish to use a consolidated distfiles directory, in which case you |
| 143 | should make /usr/dfports/distfiles a softlink to your existing distfiles |
| 144 | directory (typically /usr/ports/distfiles). |
| 145 | |
| 146 | Be sure that you have installed 'relpath' from the DragonFly sources |
| 147 | (/usr/src/usr.bin/relpath) as well as the updated /usr/share/mk files from |
| 148 | /usr/src/share/mk. As a test you can cd into /usr/ports/sysutils/cpdup and |
| 149 | build the port. Dragonfly should contain an override and you should see a |
| 150 | warning message that the DragonFly override is being build instead when you |
| 151 | build it from the FreeBSD ports. |
