I know I can give permission to use "mount/unmount" through sudo some users without password.

But how can I give permission to use "mount/unmount" only for /dev/sda2 and not for /dev/sda10?

For example, some user can execute: sudo mount -t ntfs /dev/sda2 ~/mnt/ntfs
But the same user must not have permission to execute: sudo mount /dev/sda10 ~/mnt/s10

  • the sudo command let you become root for a while. So, if you are root, shall be no limitations

  • @gio900 The point is that one wants to only allow a given user to run a specific command with a specific parameter with root privileges.

you could create a simple file:

 sudo visudo -f /etc/sudoers.d/myOverrides 

with this directive:

 User ALL = NOPASSWD:/sbin/mount -t ntfs /dev/sda2 /home/User/mnt/ntfs

This allow User to runs mount command with those parameter without entering a password.

Here is sudo manual for more details.

  • Still problem. sudo -l: User dmit may run the following commands on mintPC: (ALL : ALL) ALL (root) NOPASSWD: /bin/mount -t ntfs /dev/sda2 /home/dmit/mnt/ntfs /bin/mount -t ntfs /dev/sda2 /home/dmit/mnt/ntfs mount: only root can do that

  • You should run mount with sudo: "sudo mount -t ntfs /dev/sda2 /home/dmit/mnt/ntfs" and this will not ask you for password

You can specify arguments in the sudoers file, something like this should work:

user ALL=(ALL) /sbin/mount -t ntfs /dev/sda2 /home/user/mnt/ntfs, /sbin/umount /dev/sda2
