+         for users and groups beyond the standard owner/group/world scheme,
+         and this option selects support for ACLs specifically for tmpfs

+         If you've selected TMPFS, it's possible that you'll also need
+         this option as there are a number of Linux distros that require
+         POSIX ACL support under /dev for certain features to work properly.
+         For example, some distros need this feature for ALSA-related /dev
+         files for sound to work properly.  In short, if you're not sure,

          To learn more about Access Control Lists, visit the POSIX ACLs for
          Linux website <http://acl.bestbits.at/>.
