I have always been skeptical about sharing /usr on Debian, especially
I've always wondered is how you upgrade the remote (nfs-mounted)
systems?
* How to upgrade /bin, /lib... files?
* Can dpkg be told to not touch /usr on those machines?
* Some (pre|post)(inst|rm) scripts use files in /usr... Aren't they
guaranteed to behave in unpredictable way, if the version is /usr
aren't the one expected by those scripts?
I used lessdisk[1] in sarge, but it used to export the whole tree over
NFS.

P.S. I like the idea to use encrypted partition for the whole system,
excepts /usr.
