From 8bdc329e892f35ca19dfd07b542aa81afd855fce Mon Sep 17 00:00:00 2001 From: Anand Avati Date: Tue, 10 Dec 2013 14:28:22 -0800 Subject: posix: if brick-uid or brick-gid is not specified, do not set MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Current code would set owner uid/gid explicitly to 0/0 on start even if none was specified. Fix it.
