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

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