PR#254282 reports a problem where nullfs mounts cannot be
exported via mountd for FreeBSD 13.0.
The problem seems to be that, to do the nullfs mounts in
/etc/fstab, they require the "late" mount option, so that the
underlying filesystem is mounted (ZFS for the PR).
Adding "mountlate" to the REQUIRE list in /etc/rc.d/mountd
fixes the problem, but that results in a dependency cycle
because /etc/rc.d/lockd specifies:
- REQUIRE: nfsd
- BEFORE: DAEMON
--> which forces mountd to preceed DAEMON.
I think I know why lockd specifies:
--> I suspect that some daemon requires file locking and that
requires lockd to be running, for an NFS mounted root fs.
but I do not see any reason that lockd/statd must start after nfsd.
(This # REQUIRE has been in the scripts since they were imported
from NetBSD long long ago.)
This patch makes mountd start after mountlate, without any dependency
