Installing 64bit CentOS6 only installs x86_64 and noarch RPMS - however, I have a number of legacy 32bit apps that require a number of 32bit RPMS to be installed.
Does anyone know how to get the installer to install the 32bit versions of 64bit RPMS? i.e. in the way it does for CentOS5.
After and bit of digging, it appears to be down to a change of a default setting in yum with CentOS6
The yum config option multilib_policy is now 'best' in CentOS6 - in CentOS5 it is 'all' - which means CentOS6 will only install the x86_64 version if both a x86_64 and i686 RPM exists in the repo
I guess if I want to revert this back to 'all', I'll need to hack anaconda to add 'multilib_policy=all' to the temporary yum config file.
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.
