UsrMove and installing kernels on older releases

Hi Kay and Harald, With UsrMove now landed in rawhide, I'm assuming that you'll be wanting to commit the patch[1] that makes kernel.spec install modules into /usr/lib instead of /lib. According to my understanding, this is mostly a "put things in the new proper location" more than it is a requirement, because the symlinks should still allow a fully functioning kernel to work (and they do in my local testing). One of the things we do quite often during debug is ask users to install newer kernels on older releases. This lets us easily figure out if an issue is fixed upstream, etc. However, if the patch to install modules to /usr/lib goes in, I wonder if that will prevent people from easily being able to use such kernels on e.g. f15/f16 which obviously do not have the UsrMove feature. Admittedly I haven't looked into it much myself yet so perhaps I've missed something obvious that would allow this to still work. If there is an issue with that scenario, I'd like to skip the patch until F17 becomes the oldest supported release. With things obviously still working as-is today, I don't see much issue in doing so. josh [1] http://harald.fedorapeople.org/downloads/usrmove/kernel-usrmove.patch
