Getting koan/LiveCD running on F8
 
I had to make some small changes to get koan/LiveCD building under
Fediora 8 and then creating a Fedora 8 install under VMware.


for base.cfg the livecd tools don't seem the take the --packages flag
anymore so I added the some extras to %package and also sfdisk seemed to
want all 4 primary partions configured - although that might be down to
me building in a VMware target machine
