OK thanks for the update i am a bit confused though as i thought that
using koan i could _reinstall_ a system without the need for DHCP and
PXE - The simple fact is that right now i cant use DHCP in this specific
network and so using koan to rebuild, and thats the key i think i am
rebuilding a current running OS not bare metal, to contact the cobbler
server.
Koan contacts the cobbler server and i thought, and it seems correct,
that it builds a minimal boot kernel, this boots with IP info and then
the kickstart is downloaded negating the need for DHCP. I do similar
things in another network to rebuild people's VM's running on laptops
etc that are not covered in my DHCP setup and they rebuild fine, the
only issue is that this is a new server and o cant seem to figure out
whats wrong.
i'd like to know if i've had a misconception about koan all this time ;)
thanks
