+	  POSIX Access Control Lists (ACLs) support additional access rights
+	  for users and groups beyond the standard owner/group/world scheme,
+	  and this option selects support for ACLs specifically for tmpfs
+	  filesystems.
+
+	  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,
+	  say Y.
 
 	  To learn more about Access Control Lists, visit the POSIX ACLs for
 	  Linux website <http://acl.bestbits.at/>.
 
-	  If you don't know what Access Control Lists are, say N.
