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.

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.
141

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).
153
154	  Currently this enables support for the trusted.* and
155	  security.* namespaces.
156
157	  You need this for POSIX ACL support on tmpfs.
