Oh yeah, I forgot to mention in my own recommendation of LVM, not only 
can you allocate *more* space as needed, you can also allocate *less* 
space as needed.

Remember the example I gave for growing /home?

Well let's say you allocated 8GB at install time for /usr but the 
machine has been up and running for awhile, and you've only been using 
a little over 3G in /usr.  You wish you had only allocated 4G to /usr.  
Easy.

	1. # drop to single user mode
	2. umount /usr
	3. e2fsadm -L-4G /usr
	4. mount /usr
	5. exit

That will shrink /usr by 4G and re-allocate that space back to the 
available pool in the LVM.
