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

Robert P. J. Day206506c2011-08-03 16:21:29 -0700124 POSIX Access Control Lists (ACLs) support additional access rights
125 for users and groups beyond the standard owner/group/world scheme,
126 and this option selects support for ACLs specifically for tmpfs
127 filesystems.
128
129 If you've selected TMPFS, it's possible that you'll also need
130 this option as there are a number of Linux distros that require
131 POSIX ACL support under /dev for certain features to work properly.
132 For example, some distros need this feature for ALSA-related /dev
133 files for sound to work properly. In short, if you're not sure,
134 say Y.
