118 created on your hard drive. The files live in memory and swap
119 space. If you unmount a tmpfs instance, everything stored therein is

134
135 If you've selected TMPFS, it's possible that you'll also need
136 this option as there are a number of Linux distros that require
137 POSIX ACL support under /dev for certain features to work properly.
138 For example, some distros need this feature for ALSA-related /dev
139 files for sound to work properly. In short, if you're not sure,
140 say Y.
