relevant part of the code https://github.com/NTTCom-MS/eyp-postfix/blob/b753fb7cb459fe6db9e93ac5f517d6826fc2d2ed/manifests/params.pp#L68 so adding a facts could be a way.

but looking at multiple Ubuntu install, postfix uid seems variable. any option to let it as is?

Thanks

Hi, The real problem here is that Debian and derived like Ubuntu starts services on install by default.

There's no clean way to do it via puppet: reference, so if you want to let puppet change it just stop postfix and reapply puppet, otherwise you need to set postfix_username_uid and postfix_username_gid to the appropiate value

best regards,
