Not an elegant solution, or one that sheds any light on
the nature of the problem, but this process worked for me:
1) Removed everything from the default run level except for
the system logger and net.eth0
.
2) Rebooted and started nfs by hand successfully after the
reboot. Added nfs to the default run level.
3) Repeated steps 1) and 2) for each additional program I
wanted to add the the default run level. Everything seems
to work fine now.
