there are actually almost no filesystems, just one filesystem with many 
"upper descriptors" and separate per filesystem quota.

just to make happy those who like to have "separate" filesystem for many 
things.

i always make one filesystem for /, unless it's multiple disks config and 
i do like some data to be physically on different drive.for example highly 
loaded squid cache.
