Hmmm.   /tmp is definitely one thing I would take out of /
and put in its own partition - or at least in some other big
scratch space.   It can easily get filled with stuff which then
goes away.  But if it overfills /, it can bring the system to
its knees.  If it overfills its own system, it can make things
slow to a standstill, but usually you can still get in with root
and nuke enough to continue and at least shut things down gracefully.
