tmpfs

Description

tmpfs is a temporary filesystem on linux that purely resides in RAM. It can be used to significantly speed up file access or reduce read/write operations on a hard drive. Arch Linux by default has /tmp mounted as a tmpfs.

Usage

To mount a tmpfs, consult the manual page tmpfs(5). Some simple things are:

mount -t tmpfs -o size=10M tmpfs /mnt/mytmpfs

Since tmpfs is mounted via selecting a type from mount, all mount options apply. See mount(8).
