This directory contains subdirectories which are used as mount points for removeable media such as floppy disks, cdroms and zip disks.

Rationale |
|---|---|
|
Historically there have been a number of other different places used to mount removeable media such as /cdrom, /mnt or /mnt/cdrom. Placing the mount points for all removeable media directly in the root directory would potentially result in a large number of extra directories in /. Although the use of subdirectories in /mnt as a mount point has recently been common, it conflicts with a much older tradition of using /mnt directly as a temporary mount point. |
The following directories, or symbolic links to directories, must be in /media, if the corresponding subsystem is installed:
| Directory | Description |
|---|---|
| floppy | Floppy drive (optional) |
| cdrom | CD-ROM drive (optional) |
| cdrecorder | CD writer (optional) |
| zip | Zip drive (optional) |
On systems where more than one device exists for mounting a certain type of media, mount directories can be created by appending a digit to the name of those available above starting with ‘0‘, but the unqualified name must also exist. [16]
This directory is provided so that the system administrator may temporarily mount a filesystem as needed. The content of this directory is a local issue and should not affect the manner in which any program is run.
This directory must not be used by installation programs: a suitable temporary directory not in use by the system must be used instead.

A compliant implementation with two CDROM drives might have /media/cdrom0 and /media/cdrom1 with /media/cdrom a symlink to either of these. |
