107 Tmpfs is a file system which keeps all files in virtual memory.
108
109 Everything in tmpfs is temporary in the sense that no files will be
110 created on your hard drive. The files live in memory and swap
111 space. If you unmount a tmpfs instance, everything stored therein is
112 lost.

114 See <file:Documentation/filesystems/tmpfs.txt> for details.

125 filesystems.
126
127 If you've selected TMPFS, it's possible that you'll also need
128 this option as there are a number of Linux distros that require
129 POSIX ACL support under /dev for certain features to work properly.
130 For example, some distros need this feature for ALSA-related /dev
131 files for sound to work properly. In short, if you're not sure,
132 say Y.
