 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.

 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/>.

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

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

 146           Currently this enables support for the trusted.* and
