106	help
107	  Tmpfs is a file system which keeps all files in virtual memory.
108
109	  Everything in tmpfs is temporary in the sense that no files will be
110	  created on your hard drive. The files live in memory and swap
111	  space. If you unmount a tmpfs instance, everything stored therein is
112	  lost.
113

121	help
122	  POSIX Access Control Lists (ACLs) support additional access rights
123	  for users and groups beyond the standard owner/group/world scheme,
124	  and this option selects support for ACLs specifically for tmpfs
125	  filesystems.
126
127	  If you've selected TMPFS, it's possible that you'll also need
128	  this option as there are a number of Linux distros that require
129	  POSIX ACL support under /dev for certain features to work properly.
130	  For example, some distros need this feature for ALSA-related /dev
131	  files for sound to work properly.  In short, if you're not sure,
132	  say Y.
133
134	  To learn more about Access Control Lists, visit the POSIX ACLs for
135	  Linux website <http://acl.bestbits.at/>.

142	  Extended attributes are name:value pairs associated with inodes by
143	  the kernel or by users (see the attr(5) manual page, or visit
144	  <http://acl.bestbits.at/> for details).
145
146	  Currently this enables support for the trusted.* and
147	  security.* namespaces.
148
149	  You need this for POSIX ACL support on tmpfs.
