105 help
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.
112
113 See <file:Documentation/filesystems/tmpfs.txt> for details.

120 help
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/>.

141 Extended attributes are name:value pairs associated with inodes by
142 the kernel or by users (see the attr(5) manual page, or visit
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.
