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.
Thanks

If you use a kickstart, you can specify packages with a specific arch:
%packages glibc.i686 %end

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.

I had a problem with 32-bit rpms on 64-bit system. I tried to install krusader-2.0.0.i386 in 64-bit system, and it reported that files from openssl(I think) x86_64 conflicts with files in same package but i686. That means that there are packages that can only be install as pure 64-bit, no multilib.

Depending on how you installed you could find there were gripes when you'd only got one half of a multilib on. I think that was normally a red herring and you just had to force the two to coexist (and yum would normally just make that happen).
You get that with things like firefox, where both 32bit and 64bit provide identical files, but it's not *really* a problem.
