115 Tmpfs is a file system which keeps all files in virtual memory.
116
117 Everything in tmpfs is temporary in the sense that no files will be
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
120 lost.
121

129 help
130 POSIX Access Control Lists (ACLs) support additional access rights
131 for users and groups beyond the standard owner/group/world scheme,
132 and this option selects support for ACLs specifically for tmpfs
133 filesystems.
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.

143 Linux website <http://acl.bestbits.at/>.

151 the kernel or by users (see the attr(5) manual page, or visit
152 <http://acl.bestbits.at/> for details).

154 Currently this enables support for the trusted.* and
155 security.* namespaces.
