Starting mountd before mounting nfs disks corrects this problem and as far
as I know does not have any disadvantages.
bg mounts won't help, as daemons started in /etc/rc.local might need the
disks (apache, for example, fails to start if it cannot find log files to
write to, or document root is missing). It is possible to kludge around
this but it would be better to fix it, particularly when it is this easy
and does not effect anyone who is not doing cross-mounting (other than nfs
comes up slightly faster after a crash/reboot, which is a plus).
