sorry for beeing an idiot :-(
"ExecStopPost" NOT "ExecStartPost"

yes, it needs really the PIDFile-Param
but it is not really as stable/clean as wanted

the first time it fails and will be restarted via "Restart=always"
below my service-files and outputs

hopefully somebody is able to optimize this and provide the other netatalk
services for systemd in a way like this - for my needs it seems to be enough
and pass configurations via config-files and/or "EnvironmentFile="

interesting is that it is not failing always - see at the end outputs from a restart
