/boot 500 MB (you don't need this much but unless you remember to keep it
cleaned out you'll eventually run out of space and won't be
able to do kernel updates anymore if you don't)
<swap> twice memory up to 2G, else same size as memory
/tmp 2 GB (you probably won't need this much if all
programs on the server are well-behaved)
/ 3 GB (I know the recommendation is for more but
I've never run out of space)
/var 15 GB (this partition is no longer used for email; I've
never come close to running out of memory)
/usr 15 GB
/home balance of drive space
