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

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

 139         help
 140           Extended attributes are name:value pairs associated with inodes by
 141           the kernel or by users (see the attr(5) manual page, or visit
 142           <http://acl.bestbits.at/> for details).
 143
 144           Currently this enables support for the trusted.* and
 145           security.* namespaces.
 146
 147           You need this for POSIX ACL support on tmpfs.
