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.
