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

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

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

143           <http://acl.bestbits.at/> for details).
144 
145           Currently this enables support for the trusted.* and
146           security.* namespaces.
147 
148           You need this for POSIX ACL support on tmpfs.
