Hiya,

  Okay, I'm baffled.  What in the Ubuntu 9.07 is going on here?

# uname -a
Linux BlueBeast.localhost 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux

 Logged in as root I've edited /etc/fstab.  
I want the /Meta vfat partition completely open (unlocked).

# cat /etc/fstab
 # /Meta was /dev/sda5 
 UUID=45F2-140B  /Meta     vfat    utf8,users,noauto   0       1

# mount
 /dev/sda5 on /Meta type vfat (rw,noexec,nosuid,nodev,utf8)

# cat /etc/mtab
 /dev/sda5 /Meta vfat rw,noexec,nosuid,nodev,utf8 0 0

# ls -al
 drwxr-xr-x   3 root root 4096 1969-12-31 17:00 Meta

# chgrp -hR users /Meta
 chgrp: changing group of `/Meta/Linux/TextTest.txt': Operation not permitted 
 chgrp: changing group of `/Meta/Linux': Operation not permitted

 I can not figure out what in Ubuntu (Mint 7) stops root (#) from assigning permissions here.
Can you?
 This vfat partition was created in SuSE 9.3 and used mkdosfs to create the file system.
/Meta is a common mount point (folder?) for multiple of my Linux distros.  But it's getting harder to use.
As root, it functions okay (mostly) as a common data folder.  I want to give access to all users
of any current-booted Linux.  In SuSE 10.3 the process required a new /etc/fstab entry followed
by the chgrp command as above.  But in Ubuntu, I'm a bit lost.
Here I can see a disagreement between /etc/fstab and /etc/mtab that I can't reconcile.

  It may be a while before I can return to the PLUG mail list.  So be patient with me.
