hi folks :)

I play a little bit around with mount an umount. But there are still some things, i didnt understand.
that's what I want:

Every user should be able to unmount a special drive, that has been manually mounted by root (so that drive isnt known to fstab)

I assume that "-o users" allows umounting by all users according to man-pages:
Allow every user to mount and unmount the file system. This option implies the options noexec, nosuid, and nodev (unless overridden by subsequent options, as in the option line users,exec,dev,suid).
I try:
Code:
root@server>mount -o users /dev/hdX /mnt/hdX
so everything went ok. But if a normal user wants to umount the drive, he gets an error:
Code:
user@server>umount /mnt/hdX
umount: only root can unmount /dev/hdX from /mnt/hdX
What's the failure?
Can you help me without putting the drive into fstab?

bye, daniel
