user cannot mount?

emanresu · 11-20-2005, 05:26 PM

I have a newbie problem with mounting and unmounting. I am running gentoo 2.6.12. In /etc/fstab, I have the following:

Code:

/dev/cdrom   /mnt/cdrom   auto   noauto,user     0  0

what I intend to do is allow a user to mount / unmount the dvd drive. However, when I stick a dvd into the drive, and start typing

Code:

mount  -t iso9660 /dev/cdrom /mnt/cdrom

it says:

Code:

mount: only root can do that

but I thought the "user" option in fstab is to allow users to mount. What did I do wrong?

You sure it is not users with an s. Not a gentoo user but seen this many times here.

It is "user" in its singular form, at least according to the gentoo handbook plus a few other online sources.

here is what I found:

Code:

For more details, see fstab(5). Only the user that mounted a filesystem can unmount it again. If any user should be able to unmount, then use users instead of user in the fstab line."

in other words, "users" allows anyone to unmount a volume, while "user" only lets the original mounter to do the unmount.

but my problem is not with unmount. My problem is with mounting... please help.

just use mount /dev/cdrom

The problem is only root can specify what to mount and where, users can moint the mount point, but not specify what device to mount. They must go by the fstab.
