[vserver] newvserver question

[GuruJ]

Hi everyone,

When running the command 'newvserver', so far I have always built an 
image from an existing vserver configuration.  This has worked fine, but 
my curiosity has got the better of me:

What does selecting the options for 'Red Hat 7.3', 'Red Hat 8.0', etc. 
do?  In particular, do you need the RPMs at a particular location, or 
will just having a set of Red Hat CDs do?

Thanks,

GuruJ.
