Operating Systems Linux grant root privileges to ordinary user Post 302233999 by ankurjain on Tuesday 9th of September 2008 12:11:48 AM

From man mount :

Quote:
(iii) Normally, only the superuser can mount file systems. However, when fstab contains the user option on
a line, anybody can mount the corresponding system.

Thus, given a line
/dev/cdrom /cd iso9660 ro,user,noauto,unhide
any user can mount the iso9660 file system found on his CDROM using the command
mount /dev/cdrom
or
mount /cd
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. The owner option is similar to
the user option, with the restriction that the user must be the owner of the special file. This may be use-
ful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is
similar, with the restriction that the user must be member of the group of the special file.

The options are as follows: -o options Options passed to mount(2) are specified with the -o option followed by a comma separated string of options. See the mount(8) man page for possible options and their meanings. -u user Set the owner of the files in the file system to user. The default owner is the owner of the directory on which the file system is being mounted. The user may be a user-name, or a numeric value. -g group Set the group of the files in the file system to group. The default group is the group of the directory on which the file system is being mounted. The group may be a group-name, or a numeric value. -s snapshot The name of the snapshot to mount. In this usage pathname is the mounted root directory of the base volume containing the snapshot. DIAGNOSTICS
