Exact same question 1 allies for me (how lucky for the day hour and minute!)
1 - Noticed i386 packages (some, not all) installed along with the 64
bit ones. Is there an rpm/yum command to list the i386, and possibly
then remove the ones I def don't need that the system will allow? Are
there some of these that I *have* to have, depending on what I use the
program for? I have seperate test/updates/rawhide dir's that I mirror,
and notice in the 64 bit ones, that there are i386 packages, as I guess
those are needed depended on if i386 is what is needed to go along with
the 64 bit ones?
