In case anyone needs to do this - here is what I've done: As I install over NFS from a local copy of the distro, I created a directory called 'RHupdates' at the top level of the install tree and copied in the file 'yuminstall.py' from the anaconda RPM to that directory. I edited the RHupdates/yuminstall.py file and added after line 1186: multilib_policy=all i.e. that line gets added to the /tmp/anaconda-yum.conf file anaconda uses to do the install via yum (files in the RHupdates directory will override files of the same name used by anaconda). I guess I could have done something similar via a kickstart file (which I haven't tested) - e.g. %pre echo "multilib_policy=all" >> /tmp/anaconda-yum.conf After the install, I added the same "multilib_policy=all" line to /etc/yum.conf - so a subsequent 'yum update' will update the 32bit packages as well.
