Well, the only way to set a kernel config parameter is to rebuild the kernel. There might be some way to extract the built-in initramfs (every kernel has one) and replace it with the new one without rebuilding it, but I doubt most users would prefer that we mount /boot and start modifying their kernel images. Changes to grub.conf will only be properly merged if /boot is mounted, if grub is installed (don't laugh - I checked and since my system was migrated so many times I don't actually have the package installed any longer), and the user actually merges the changes in. Fiddling with grub.conf isn't exactly risk-free either. I think something like this is best handled via news. Note also that depending on your definition of "broken" the separate /usr situation is already broken. It will probably steadily become more broken over time, so when it stops booting altogether for any particular user might happen anytime from a year ago to never. Rich
