/cdrom /media /mnt

/media : Mount point for removeable media

Purpose

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.

Specific Options

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]

/mnt : Mount point for a temporarily mounted filesystem

Purpose

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.

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