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.

130      POSIX Access Control Lists (ACLs) support permissions for users and

132
133      To learn more about Access Control Lists, visit the POSIX ACLs for

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