From a298ae49a77f528b0d57e013343473bb5162cd61 Mon Sep 17 00:00:00 2001 From: Marco Amadori Date: Sun, 28 Sep 2008 00:51:04 +0200 Subject: Implemented a persistence exclude list. * This finally enables one of the most requested feature to exclude things like disk caches and temporary files from the persistence images in order to speed things up and saves precious writes of flash based storages.
