I'm not sure its directly applicable to x86_64 that said, I went looking on my RHEL AS 4 system, which is the only 64bit install I have available at the moment but I can't figure out how to get `up2date` to do the equivalent of a `yum groupinfo`... I can list the groups (up2date --show-groups) but not whats in them. if someone has a CentOS4 x86_64 install handy, they could answer your question with the output of... $ sudo yum groupinfo "Compatability Arch Support" $ sudo yum groupinfo "Compatability Arch Development Support" $ sudo yum groupinfo "Legacy Software Development"
