Building OpenSolaris ISOs# Oct 22, 2008
There are three main things you're most likely to want to do: build IPS itself, populate an IPS repository, and build an install ISO based on that repository. First, you'll want a copy of the IPS gate:
hg clone ssh://[email protected]/hg/pkg/gate pkg-gateFor some of my testing, I wanted to test some changed packages. So I mounted a Nevada DVD on /mnt/, then, using mount -F lofs, replaced some of the package directories with ones I'd built previously with my fixes. This effectively gave me a full Nevada DVD with my fixes in, avoiding the horrors of making one. I then cd pkg-gate, and run something like this:
$ cat build-ips export WS=$1 export REPO=http://localhost:$2 unset http_proxy || true set -e echo "START `date`" cd $WS/src make install packages cd $WS/src/util/distro-import export NONWOS_PKGS="/net/paradise/export/integrate_dock/nv/nv_osol0811/all \ /net/paradise/export/integrate_dock/nv/nv_osol0811/i386" export WOS_PKGS="/mnt/Solaris_11/Product/" export PYTHONPATH=$WS/proto/root_i386/usr/lib/python2.4/vendor-packages/ export PATH=$WS/proto/root_i386/usr/bin/:$WS/proto/root_i386/usr/lib:$PATH nohup pkg.depotd -p $2 -d /var/tmp/$USER/repo & sleep 5 make -e 99/slim_import echo "END `date`" $ ./build-ips `pwd` 10023
In fact, since I was running on an older version Nevada (89, precisely), I had to stop after the make install and change src/pyOpenSSL-0.7/setup.py to pick up OpenSSL from /usr/sfw:
IncludeDirs = [ '/usr/sfw/include' ] LibraryDirs = [ '/usr/sfw/lib' ]
(If /usr/bin/openssl exists, you don't need this). So, after this step, which build the IPS tools (and SVR4 package for it), it moves into the "distro-import" directory. This is really a completely different thing from IPS itself, but for convenience it lives in the IPS gate. Its job is to take a set of SVR4 packages (that is, the old Solaris package format) and upload them to a given IPS network repository: in this case, http://localhost:10023.
So, making sure we use the IPS tools we just built, we point a couple of environment variables to the package locations. "WOS" stands for, charmingly, "Wad Of Stuff", and in this context means "packages delivered to Solaris Nevada". There's also some extra packages used for OpenSolaris, listed here as NONWOS_PKGS. I'm not sure where external people can get them from, though.
The core of distro-import is the solaris.py script, which does the job of transliterating from SVR4-speak into pkgsend(1)-speak. As well as a straight translation, though, a small number of customisations to the existing packages are also made to account for OpenSolaris differences. These are done by dropping the original file contents and picking them up from an ad-hoc SUNWfixes SVR4 package built in the same directory.
Of course, each build has its differences, so they're separated out into sub-directories. As you can see above, to run the import, we make a 99/slim_import target. This basically runs solaris.py for every package listed in the file 99/slim_custer. This list is more or less what makes up the contents of the live CD. Also of interest is the redist_import target, which builds every package available (see http://pkg.opensolaris.org). By the way, watch out for distro-import/README: it's not quite up to date.
Another super useful environment variable is JUST_THESE_PKGS: this will only build and import the packages listed. Very useful if you're tweaking a package and don't want to re-import the whole cluster!
At the end of this build, we now have a populated IPS repository living at http://localhost:10023. If we already have an installed OpenSolaris, we could easily use this to install individual new packages, or do an image update (where ipshost is the remote name of your build machine):
# pkg set-authority -P -O http://ipshost:10023 myipsrepo # pkg install SUNWmynewpackage # or... # pkg image-update
If we want to test installer or live CD changes, though, we'll need to build an ISO. I did this for the first time today, and it's fall-over easy. First you need an OpenSolaris build machine, and type:
# pkg install SUNWdistro-const
Modify slim_cd.xml to point to your repository, as described here. It's not immediately obvious, but you can specify your URL as http://ipshost:10023 if you're not using the standard port, like me. Then:
# distro_const build ./slim_cd.xml
And that's it: you'll have a fully-working OpenSolaris ISO in /export/dc_output/ (I understand it's a different location after build 99, though). I never knew building an install ISO could be so simple!
