+ /etc/live-persistence.binds
+
+This optional file (which resides in the rootfs system, not in the live media)
+is used as a list of directories which not need be persistent: ie. their
+content does not need to survive reboots when using the persistence features.
+
+This saves expensive writes and speeds up operations on volatile data such as
+web caches and temporary files (like e.g. /tmp and .mozilla) which are
+regenerated each time. This is achieved by bind mounting each listed directory
+with a tmpfs on the original path.
