>Description:
	Using RELENG_5_2, but the HEAD files have the same problem.  On
	booting fsck seems to want to be scheduled for all file systems
	listed in fstab, including nfs.  This produces an error about
	fsck_nfs ... or similar.

	The below patch takes the code frmo mountcritlocal to remove the
	network file systems from the list.
