 I just wanted to make sure if the case is limited to background NFS
 mount or not.

 rc.d/mountlate just tries to mount the filesystems that are not
 mounted yet at that time in addition to the "late" ones, not always
 to mount the same set twice.  If it is a bug, it is better to simply
 fix -l to exclude not-yet-mounted ones without "late" keyword than
 adding another option.
