I have 4 different flavors of fedora on my system, with f8 x86_64 in use 99.9% of the time, but f8 i386 and f7 x86_64 and i386 available for testing (which I sometimes need to do). I was just wondering if some magical combination of set-arch and chroot and the yum downloadonly plugin could be used to get all the appropriate updates downloaded for my non-active partitions, so the next time I happen to boot, I could run yum update and it would find it already downloaded the updates it needs, so all it would need to do is install them.
