At least for some servers, a separate /var is often recommended.
Then if you get some rogue process, or buggy script, or someone
breaking into the box producing massive log files or spool files,
/var fills up but / and /tmp are OK so your system may stay up.

I use a separate /var on my desktop box, just for safety, but
this is almost certainly unnecessary for most users.
