LVM Question

[Mark McCulligh]

Hi Group,

I am building a server using Software Raid and plan to setup LVM 
(Logical Volume Manager) on the Raid and have a question.  I was reading 
the Red Hat  manual on LVM and in their example they created a Volume 
Group with Logical Volumes swap, /home and / .   Why would you what to 
create the /home mount point?  Would not it be better just to have the 
swap and / ? Then /home, /usr. /var, etc.. would share the / storage 
space. 

Just wondering why would you use LVM, then fix the size of your /home?

Thanks,
Mark.
