(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 useful 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.
