Multilib Middle-Ground

Korean language desktop install by using the yum group.  THIS IS A BIG
PROBLEM OUTSIDE OF LIVECD.

... 'and font'? The scim change changes fonts? O RLY?

This is *exactly* what I said. You're saying we should do something
special for an input method (for GTK only) that we don't do for QT input methods, NSS modules, PAM modules, etc.

Then I guess we are really not that much worse off. It is impossible for yum groupinstall to "fix" these problems in Fedora 9.

This points to a more general problem: We were not happy with having a huge pile of unnecessary i386 packages so our solution was to completely eliminate them from the default install. We went TOO FAR overcompensating for the previous broken multilib behavior.

Dependencies or a comps multilib whitelist could be a nice middle-ground. Some users want to be i386-free. Other users want a tiny set of expected packages to be multilib to avoid confusion. The current yum option is either all or none.

Perhaps we need a third option like "smart" which uses a multilib whitelist that can be updated via repodata. Anaconda and other GUI interfaces can allow the user to choose between "smart" and "100% i386 free". This way "yum groupinstall korean-support" can install everything the user expects.

This avoids the lose of:
- expecting the user to manually install a complicated set of arch-specific packages because they can't use yum groupinstall - expecting the user to change the yum multilib priority option and subject themselves to a huge pile of unnecessary crap that they will never need.

No time to do this before F9.
