>Description:
	mount_nfs can fail to mount even critical file systems under
	some conditions.
>How-To-Repeat:
	Try mounting mounting a file system from a non-existent host.
>Fix:
	Well, the bug should be fixed in mount_nfs, but mentioning it
	in the man page seems at least appropriate for now. The
	attached patch to mount_nfs.8 adds that.
