with user in fstab, the user that mounted should be able to umount it, like Ron asked, what is your error? > > Another thing that is not clear to me is the difference between the `user' and > `users' options of `mount' command. This one is simple, user = a user can mount it, the SAME user can umount it. users = a user can mount it, ANY user can umount it. > > But now I understand why the problem occurs trying to mount the drive when the > umts device is already plugged in: for some reason, although the umts device > is mapped into /dev/ttyUSB0, /dev/sda comes to be busy.
