You want an ugly workaround? How about keeping your separate /usr, but
keep a very stripped-down copy (just the stuff needed during boot) under
the /usr directory on your root file system. That will, of course, all
be hidden when the separate /usr file system gets mounted.
OK, so how do you maintain the contents of that buried /usr while the
system is running? Time to get tricky with bind mounts:
1. Create a directory /usr0.
2. Arrange /etc/fstab so that the /usr directory gets bind mounted onto
/usr0 _before_ the real /usr gets mounted. (Note: I haven't done
any testing to see if you can actually ensure that the mounts get
done in this sequence during the auto mounting of local file
systems.)
Now /usr0 is your window into that overlaid /usr directory. You can use
rsync with the "--existing" option to update just the files that you
placed in that root fs /usr.
If you ever umount /usr0, though, there's no way to regain access
without rebooting.
As an extra-credit exercise, figure out how to set this up on a running
system without booting from a rescue disk.
