Thanks >Azmi That's probably because you are running some programs off /usr, maybe the X applications in /usr/X11R6? You may need to look at other network filesystems or some way of getting a backup server to take over at the primary's IP address and then sending out an ARP packet to refresh the caches on the clients. I think this is explained in some detail in that HOWTO. This problem is starting to move into high availability distributed filesystems and so the problem is not netbooting specific anymore.
