From ae4523336ac06e3ff7cc7b416fad9e57998c6b54 Mon Sep 17 00:00:00 2001 From: Tim Waugh Date: Fri, 3 Jul 2009 10:29:01 +0100 Subject: [PATCH 2/3] Don't unnecessarily try to change a file context As pointed out by Tim Waugh here: https://bugzilla.redhat.com/507555 We shouldn't bother trying to set the context of a file if it already matches what we want.
