Installing a chroot environment was quite easy.

mkdir /chroot/cooker
urpmi basesystem --root /chroot/cooker

Undocumented feature (not in man page or --help)?

True... But, if you think about it: how does mdk install a system?

I know rpm can --root.

yep

BTW, I have an installed 8.2 on a partition, and rpm built, but I don't
know where it put the packages. If my %_topdir is on a seperate
partition, do I need to mount that partition with --bind under the chroot?

What I do is I've made a user account in the chroot, and I let rpm --rebuild run from there...

copy the src.rpm to somewhere in the chroot (otherwise it can't be accessed --> I'd rather not run automount in the chroot)
cp /mirrors/${2}/SRPMS/${1}.src.rpm \
${CHROOT_PATH}/var/tmp/

run the rpm --rebuild command in the chroot:
                               sudo /usr/sbin/chroot ${CHROOT_PATH} \
                               su -l cooker \
                               -c "rpm --rebuild /var/tmp/${1}.src.rpm" \
                               &> ${buildoutput}/${2}/${HOSTTYPE}/${1}

Move the resulting rpm's back to the host system:
                               mv ${NHOME}/RPM/RPMS/${HOSTTYPE}/* \
                               ${HOME}/RPM/RPMS/${HOSTTYPE}/
                               mv ${NHOME}/RPM/RPMS/noarch/* \
                               ${HOME}/RPM/RPMS/noarch/

remove the temporary copy of the src.rpm file:
                               rm -rf ${CHROOT_PATH}/var/tmp/${1}.src.rpm

For more details, see the script.

I've adapted slbd to run in a chroot environment. See:
http://eijk.homelinux.org/build/bin/slbd.sh

Hmm, maybe I'll take a look, but I really want to be able to build on
9.0, 8.2 and 8.1, since the only machines I have that run those releases
that I am prepared to have compilers on are too slow (P133 etc, samba
build takes 6+ hours).

Should be no problem...

If you need help setting it up... you know where to find me :-)
