So quotarpc.service is only supposed to run if rpcbind is installed? I think what you want here then is Wants/After + a Condition [1]. i.e. [Unit] Wants=rpcbind.service After=rpcbind.service ConditionFileIsExecutable=/sbin/rpcbind .... [1] man systemd.unit -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
