There has been previous thought given to this and it comes down to
this...

When the system gets wedged and you need to use single-user mode to
unfork it you don't want to mount any more filesystem than needed, just
the R/O's.

For Solaris I used to use a cheat-sheet, but I don't know where that is
anymore. What I do know is I always keep the following as separate
filesystems...
/var (for many reasons, esp. since it grows)
/home (cause it grows wildly and you DON'T want your / hitting 100%
ever).
/export/home if you are using it instead of home
/swap (obviously)
/boot
/usr

If space is very tight and the system might be dynamic in nature (a
workstation as opposed to a file server) you might consider the
following: put /tmp /bin /sbin somewhere other than root. These can grow
too. But this is just space paranoia for very tight storage.
