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

119 help
120 POSIX Access Control Lists (ACLs) support additional access rights
121 for users and groups beyond the standard owner/group/world scheme,
122 and this option selects support for ACLs specifically for tmpfs
123 filesystems.
124
125 If you've selected TMPFS, it's possible that you'll also need
126 this option as there are a number of Linux distros that require
127 POSIX ACL support under /dev for certain features to work properly.
128 For example, some distros need this feature for ALSA-related /dev
129 files for sound to work properly. In short, if you're not sure,
130 say Y.

144 Currently this enables support for the trusted.* and
