You've already seen answers regarding what dirs must be on the root
partition. I want to point out that if you are setting up a multiuser
system, or any system which needs to enforce filesystems quotas, quotas
are enforced per filesystem.  Thus /tmp, /var/tmp, /home, and possibly
/var/spool (and/or subsets of var/spool) should be on seperate
filesystems.  Any samba or NFS shared directories are candidates for
this rule as well.

I also set up seperate filesystems for directories that could
conceivably be filled up (maliciously or otherwise); these include
/var/log, /usr/local/src, and /opt if you are installing third party
software.
