 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 additional access rights
 131           for users and groups beyond the standard owner/group/world scheme,
 132           and this option selects support for ACLs specifically for tmpfs
 133           filesystems.
 134
 135           If you've selected TMPFS, it's possible that you'll also need
 136           this option as there are a number of Linux distros that require
 137           POSIX ACL support under /dev for certain features to work properly.
 138           For example, some distros need this feature for ALSA-related /dev
 139           files for sound to work properly.  In short, if you're not sure,
 140           say Y.
 141

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

 150           Extended attributes are name:value pairs associated with inodes by
