>Description:
I updated my 6-STABLE system on 3rd February, the previous rebuild being on 2nd 
January.

I have the following line in my /etc/fstab file, for mounting a removable USB
flash drive with an MSDOSFS filesystem:

  /dev/da0s1 /flash msdosfs rw,noauto,-m=0777 0 0

Following yesterday's update, the command "mount flash" fails with the error:

  mount_msdosfs: /dev/da0s1: Invalid argument

and the following kernel error is logged:

  mount option <auto> is unknown

If I remove the noauto option then the mount succeeds normally.

I would guess that this change is due CVS revision 1.36.2.1 to
src/sbin/mount_msdosfs/mount_msdosfs.c (Sun Jan 28 18:01:28 2007 UTC by rodrigc).
 
>How-To-Repeat:
List an msdosfs filesystem in /etc/fstab with "noauto" amongst the options.
Attempt to mount it with "mount /mountpointname".
