Using building Web Servers or Email Servers, for the /home using came 
grow fast (sometimes make a /www folder).  I was just wondering why in 
Red Hat's manual they would create a LVM Volume Group, then in the 
Logical Volumes they add a fixed /home directory?  Because the /home can 
grow the most would not it be better to have it under the / Logical 
Volume for you do not run out of space. Just a little puzzled by Red 
Hat's Example.
