For those who care, you are just not supposed to enable eth0 in /etc/network/interfaces. I thought it wasn't showing up in ifconfig without doing that, but I must have been mistaken.
Another question: what is the best way of making the NFS filesystem read-only so that the N ROACH boards do not conflict with one another? I modified fstab to have this line: rootfs / rootfs ro 0 0 There are a number of complaints along the way in bootup, however. Would it be better to edit /etc/rcSimple to remount read-only after boot?
