From c6563f0523bdd24a88bb4766509494c23d43e38f Mon Sep 17 00:00:00 2001
From: Warren Baker <warren@decoy.co.za>
Date: Mon, 31 Jan 2011 18:40:03 +0200
Subject: Remove manual user deletion (its handled by the pkg removal process).
 Also added Cache Restoration support, so the existing cache is dumped to disk
 and restored in case of a service restart, reboot or shutdown of the server.
