+From c09d377cd3b91c4c4360ebfab5be37f6296ff26a Mon Sep 17 00:00:00 2001

+Subject: [PATCH] postfix: add preliminary setting
+
+post-install call postconf commands to modify main.cf. When multiple
+parameters to postconf, the order of those parameters in main.cf is random.
+Then it will reproduce random results in rootfs file(sample-main.cf). To
+fix this, add preliminary setting in main.cf.
+
+Upstream-Status: Inappropriate [this is the use of post-install,
+upstream is not affected]
+
+Signed-off-by: Jinfeng Wang <jinfeng.wang.cn@windriver.com>
