No effort required to protect anything in /etc from updates. A new humongous postfix config file gets installed in /etc/postfix/._cfg<whatever> and your custom config file remains untouched. It just works (tm). But you know that. I’m thinking I don’t at all understand your issue. > > I don't want to faff about with special copies, backups, origs etc. > Everything should "just work (tm)". Fair enough! Not expecting that my faffing about would appeal to anyone but me. ;) John
