I checked my notes and can add some detail. Until squeeze, the system
(live-boot) tried to mount the NFS root from the same IP address as the
TFTP server. In squeeze, however, it (dracut) defaults to the DHCP
server's IP address. In my setup, the DHCP server is separate from the
TFTP+FAI server, so specifying an explicit IP address became necessary.
