To gain access to files on a device, you must first tell it where in the directory tree you would like those files to appear (mount point). This process is called mounting a filesystem.
- Devices must be mounted before they can be accessed.
- Devices must be unmounted before they can be "ejected" (you should not eject a mounted floppy).
- Mount a filesystem.
- Unmount a filesystem.
The system administrator can control which file systems are mounted
at boot time, pre-determine the mount points for specific file systems,
and allow some file systems to be mounted by normal users.
This is configured in
/etc/fstab, which includes the
- mount point
- filesystem type
noauto: not done at boot time
ro: read-only device
users: any user can mount it
