Setting up an OpenBSD release builder

A release builder for OpenBSD is quite useful when you have a farm of systems that you have to maintain.

However, due to the nature of the build system one can only build and maintain stable updated releases for a particular tree only. This makes the need for two build systems obligatory. One system will follow the “STABLE” and one build system will have to follow the “snapshot” in order to avoid kernel incompatibilities.

Our own stable release builder, is a VirtualBox virtual machine named builder58 with IP 172.20.1.1 (this is not a static IP). This system is powered off most of the time and only boots up in order to fetch an updated tree and build an up2date release.

XXXFIXMEXXX We need a schedule to perform these tasks (eg daily sync and rebuild?)

Some of the system details to ease in deciding

Fetch the packages

mkdir -p /home/tgzs && cd /home/tgzs
for i in src sys ports xenocara
do
 ftp ftp://ftp.openbsd.org/pub/OpenBSD/$(uname -r)/$i.tar.gz
done

cd /usr/src
tar zxpf /home/tgzs/src.tar.gz
tar zxpf /home/tgzs/sys.tar.gz
cd /usr
tar zxpf /home/tgzs/xenocara.tar.gz
tar zxpf /home/tgzs/ports.tar.gz

export CVSROOT=anoncvs@ftp5.eu.openbsd.org:/cvs
cd /usr
cvs -qd$CVSROOT checkout -rOPENBSD_5_7 -P src ports xenocara

Later you can update the repository by executing

cd /usr/src && cvs -qd$CVSROOT up -rOPENBSD_5_7 -Pd
cd /usr/xenocara && cvs -qd$CVSROOT up -rOPENBSD_5_7 -Pd
cd /usr/ports && cvs -qd$CVSROOT up -rOPENBSD_5_7 -Pd

Building the new release

#!/bin/ksh
#
# Perform all operations required to produce a new updated release
# The new release is left under a folder /altroot/YYYYMMDD
export LMAJOR=5
export LMINOR=7
export LBRANCH=OPENBSD_${LMAJOR}_${LMINOR}
export CVSROOT=anoncvs@ftp5.eu.openbsd.org:/cvs

cd /usr/src/sys/arch/`machine`/conf
config GENERIC.MP
cd ../compile/GENERIC.MP
make clean && make && make install
cp /sbin/reboot /sbin/oreboot
rm -rf /usr/obj/*
cd /usr/src
make obj
cd /usr/src/etc
env DESTDIR=/ make distrib-dirs
cd /usr/src
make build
export DESTDIR=/usr/dest
export RELEASEDIR=/usr/rel
rm -rf ${DESTDIR} ${RELEASEDIR}

cd /usr/src/etc && make release
cd /usr/src/distrib/sets
sh checkflist
rm -rf /usr/xobj/*
cd /usr/xenocara
make bootstrap

make build
export DESTDIR=/usr/xdest
export RELEASEDIR=/usr/rel
rm -rf $DESTDIR
mkdir -p $DESTDIR ${RELEASEDIR}
make release
cd $RELEASEDIR
cksum -a sha256 *tgz > SHA256
/bin/ls -nT > index.txt
mv $RELEASEDIR /altroot/$(date +"%Y%m%d")
echo "If /sbin/reboot fails use the /sbin/oreboot command"

Once this is finished the newly created files can be found under amd64.org/ folder.
