 119           Tmpfs is a file system which keeps all files in virtual memory.
 120
 121           Everything in tmpfs is temporary in the sense that no files will be
 122           created on your hard drive. The files live in memory and swap
 123           space. If you unmount a tmpfs instance, everything stored therein is
 124           lost.

 134           POSIX Access Control Lists (ACLs) support additional access rights
 135           for users and groups beyond the standard owner/group/world scheme,
 136           and this option selects support for ACLs specifically for tmpfs
 137           filesystems.
 138
 139           If you've selected TMPFS, it's possible that you'll also need
 140           this option as there are a number of Linux distros that require
 141           POSIX ACL support under /dev for certain features to work properly.
 142           For example, some distros need this feature for ALSA-related /dev
 143           files for sound to work properly.  In short, if you're not sure,
 144           say Y.
 145

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

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