[et-mgmt-tools] koan bombs on FC8 install

[Tom Brown]

Hi

I am trying to use koan to provision an FC8 box - The box is currently 
running RHEL5.1 and i can rebuild it to this fine.

If i try to get koan to switch the distro to FC8, this happens on x86_64 
and x86_32, i get this

# koan -s 192.168.12.161 -r

Anyone have any clue as to why this is ?
