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

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

 140         help
 141           Extended attributes are name:value pairs associated with inodes by

 143           <http://acl.bestbits.at/> for details).

 145           Currently this enables support for the trusted.* and
