[Bug 620382] [NEW] smbmount allows mounting the same ressource multiple times on the same mountpoint

[nomike]

Public bug reported:

Binary package hint: samba

I'm running "Ubuntu 10.04.1 LTS".
I tried to mount a network share using the following command:

sudo smbmount //P1at.s-group.cc/Shared/Global/ /mnt/ -o
user=s4773,dom=i0188

I realized I could not write to the share as a regular user so I ran

sudo smbmount //P1at.s-group.cc/Shared/Global/ /mnt/ -o
user=s4773,dom=i0188,remount,rw,user

two times.
This resulted in "//P1at.s-group.cc/Shared/Global/" being mounted to "/mnt/" 3 times.

Running " LC_ALL=C umount /mnt/" produced "umount: it seems /mnt is mounted multiple times".
Running "sudo umount /mnt/" unmounted one of the mounts.

The "mount" commando still outputs:
...
//P1at.s-group.cc/Shared/Global/ on /mnt type cifs (rw,mand)
//P1at.s-group.cc/Shared/Global/ on /mnt type cifs (rw,mand)


Running "sudo umount /mnt/" again produces:

This utility only unmounts cifs filesystems.
This utility only unmounts cifs filesystems.
This utility only unmounts cifs filesystems.

I did not find a way to umount them and rebootet my System.
