pkgsrc has an advanced system to build each package in isolation of the world except for its stated dependencies. This is a good thing and helps package maintenance tremendously. It makes bulk building a little harder. In keeping with its philosophy, the new style (pbulk style building) requires bootstrapping a new pkgsrc instance (i.e. new prefix that is normally /usr/pkg), e.g. /usr/pbulk. The bulk build process needs to work in /usr/pkg, but that's where your currently installed packages live. So we backup the old tools from /usr/pkg and then restore them after. There are a few other things that need to happen, so we created a script to automate the process.
For more info on pbulk style bulk builds, see the following resources:
As for the minix specifics, there are a few steps that involve some variables that shouldn't be made up on the spot all the time, so there is a script in pkgsrc that takes care of this for Minix. The script is /usr/pkgsrc/minix/pbulk.sh It executes the build in several phases detailed below. Through the use of command line options, you can run any phase individually with the –phase-name argument or run them all with the –all argument.
We are going to run the pbulk process in a minix chroot jail. This has a few advantages:
This needs quite a lot of disk space though. At least 3GB extra for the jail currently.
Assuming pkgsrc is created in /usr/pkgsrc:
# cd /usr/pkgsrc/minix/ # sh pbulk-jail.sh -A
This will invoke /usr/src/tools/release.sh, use git to checkout the latest version of the minix tree, build it in a jail hierarchy at /usr/pbulk-jail, copy the host pkgsrc tree there to re-use its objects, and retrieve the latest pkgsrc tree from the pkgsrc repository, and invoke pbulk.sh –all in the chrooted jail.
When the script finishes, you'll have some packages in /usr/pkgsrc/packages/ in the jail. Note, the bootstrapping and binary kit creation takes a while. To do a bulk build of just the misc/figlet package from scratch takes over an hour.
The pbulk-jail script will mkfs and mount a new filesystem for the jail if you want; use the -d option to specify a device, and the jail script will umount it, mkfs it, and mount it, and build a jail on it etc.
# sh pbulk-jail.sh -d/dev/c0d0p2s3 -A
The script will automatically customize the jail directory name based on the devname, so starting multiple bulk builds at on different filesystems is ok.
In the jail, there are several opportunities to customize the build. You can decide which packages to attempt building by listing them in /usr/pkgsrc/minix/limited_list.pbulk. You can set various pbulk parameters (package upload location, reports, etc.) in /usr/pkgsrc/minix/pbulk.conf. pbulk.conf is installed to /usr/pbulk/etc/pbulk.conf during the bootstrap step, so if you want to do further modifications later, be sure to edit /usr/pbulk/etc/pbulk.conf. The various /usr/pkgsrc/minix/mk.conf* files can be edited as well.
There isn't good support for saving your customisations though, so you can't update the pkgsrc tree and keep your edits easily currently.
