Do we care about /sbin /bin linked to /usr/lib ?

I use a separate (but not shared) /usr on my servers, and I mount it
read-only. My reasoning is that / has to be read-write still for some
things (root's home directory, /etc/passwd and /etc/shadow, etc.). I
keep a small / that is read-write, but having a good chunk of the
installed stuff in /usr mounted read-only makes it a little "safer"
(i.e. an attacker would have to remount it to modify it, filesystem
corruption is unlikely on a read-only FS, etc.).

I don't speak for anybody but myself - that's enough trouble.
