On any machine which allows general users to log in, I strongly
recommend making separate file systems for /, /usr, /tmp, and /home,
plus any other areas you expect to grow large. Keeping / and /usr
separate prevents people from playing "ln" tricks to gain root
access. Keeping /tmp separate helps prevent /tmp from breaking
your system when it fills up (note that I say "when" and not "if").
Keeping the users on a separate partition helps keep them under
control because you can do things like mount the partition with
the "nosuid" attribute. The only time I ever create a machine with
a single large partition is when I am creating a dedicated server
machine that will only allow logins from trusted staff members.
