Maybe the work day is already to long. I can not find a solution for following requirement. How to apply a "Requires" with an instantiated service. Example: a at .service b.service a at .service is started as a at host1.service and b.service must be started after a at host1.service but the unit will be differently parameterized (depended of the region). So I want to generalize the requires statement. My dropin file in ./b.service.d/dep.conf looks like [Unit] Requires="a@*.service" This just produces following error: 'Failed to add dependency on "a@*.service", ignoring: Invalid argument' I use also a Before=b.service statement for a at .service but that is not enough. Any hints? -- Thanks, Leon
