     rootless-build-nulling-ownership sequence is activated.
+  * dh_usrlocal: When R³ is enabled, ignore the ownership/mode

-If the directories found in the build tree have unusual owners, groups, or
-permissions, then those values will be preserved in the directories made by
-the F<postinst> script. However, as a special exception, if a directory is owned
-by root.root, it will be treated as if it is owned by root.staff and is mode
-2775. This is useful, since that is the group and mode policy recommends for
-directories in F</usr/local>.
+In a R³-enabled build, the directories in F</usr/local> will have ownership
+root:staff and the mode will be 02775.  These values have been chosen to
+comply with the recommendations of the Debian policy for directories in
+F</usr/local>.
+
+In R³ legacy mode, the owners, groups and permissions will be preserved with
+one exception.  If the directory is owned by root:root, then ownership will
+be reset to root:staff and mode will be reset to 02775. This is useful, since
+that is the group and mode policy recommends for directories in F</usr/local>.
