-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]
