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

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

 137           Linux website <http://acl.bestbits.at/>.

 143         help
 144           Extended attributes are name:value pairs associated with inodes by
