I have always been skeptical about sharing /usr on Debian, especially
I've always wondered is how you upgrade the remote (nfs-mounted)
* 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



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