119 Tmpfs is a file system which keeps all files in virtual memory.

121 Everything in tmpfs is temporary in the sense that no files will be
122 created on your hard drive. The files live in memory and swap
123 space. If you unmount a tmpfs instance, everything stored therein is
124 lost.

138
139 If you've selected TMPFS, it's possible that you'll also need
140 this option as there are a number of Linux distros that require
141 POSIX ACL support under /dev for certain features to work properly.
142 For example, some distros need this feature for ALSA-related /dev
143 files for sound to work properly. In short, if you're not sure,
