>Description:

FreeBSD-2.1.5, mount behaves very strangely, after making a mistake
in my fstab and running mount -av several times I get the following:

My fstab is:

>How-To-Repeat:

Not 100% sure - will keep an eye out, I think that it occurs when making 
a failed attempt to mount all partitions, ie I saw after I had edited
fstab a number of times to get the mount points right.

>Fix:
	
Reboot
