Here is a complete example of how to maintain multiple main.cf files
that share common content.
Contents of /etc/postfix-shared/makefile:
=========================================
/etc/postfix1/main.cf: /etc/postfix-shared/main.cf main.cf-private
cat /etc/postfix-shared/main.cf main.cf-private > /etc/postfix1/main.cf
postfix -c /etc/postfix1 reload
/etc/postfix2/main.cf: /etc/postfix-shared/main.cf main.cf-private
cat /etc/postfix-shared/main.cf main.cf-private > /etc/postfix2/main.cf
postfix -c /etc/postfix2 reload
Command to update Postfix:
==========================
$ cd /etc/postfix-shared
$ vi main.cf
$ make
More details in the make(1) manpage. It is available since 1976 or so.
