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

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

141         help
142           Extended attributes are name:value pairs associated with inodes by
143           the kernel or by users (see the attr(5) manual page, or visit
144           <http://acl.bestbits.at/> for details).
145 
146           Currently this enables support for the trusted.* and
147           security.* namespaces.
148 
149           You need this for POSIX ACL support on tmpfs.
