I patched casper's 23networking script so it is now possible to boot without automatic dhcp discovery.
When you use the "nodhcp" boot option all networking configuration is saved to another file - /etc/network/interfaces.casper.
The original file - /etc/network/interfaces (which should be pre-configured) is then used by the system.
I also removed the second loop over the interfaces (eth0 eth1 eth2 ath0 wlan0), because it is redundant and I can't see any added value for this... someone please tell me if i'm wrong.
The patch is against casper 1.66+debian-1
