Mounting HDD still requires root permission [SOLVED]

Hi all,

I'm using ArchLinux on an external harddrive so I can work machine independant. From time to time I need to mount some of the internal harddrives but I didn't want to create a fstab entry for every possible drive. So I added my user to a group that is allowed to use mount and umount without permission (via visudo).

%users ALL=NOPASSWD: /usr/bin/mount
%users ALL=NOPASSWD: /usr/bin/umount

The drives are owned by group disk where my user was also added to get r/w permission. And I created a mountpoint directory in /home/<username> to avoid struggle with the file systems access rights.

When trying to mount a drive with

mount /dev/sda2 ~/mnt

the system keeps telling me that only root can do that.

When using sudo it works. What did I miss?

Thanks in advance.

Isn't that the expected behavior?

No, you didn't. You gave that group permission to run those two commands without entering a password when running them with sudo. It doesn't change the permissions/functionality of the binaries in question.

I think you probably missed this: https://wiki.archlinux.org/index.php/Udisks

Ah ok, that's what I got wrong. I thought I could use mount without the prepending sudo after the modifications. Thanks for pointing that out.
