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. This patch removes "nfsd" from REQUIRE for lockd and statd, then adds mountlate to REQUIRE for mountd, to fix this problem. Having lockd REQUIRE nfsd was done in the NetBSD code when it was pulled into FreeBSD and there does not seem to be a need for this. In case this causes problems, a long MFC has been specified.
