How do I list a systemd timer?

To list all timers (including inactive), use systemctl list-timers –all . The status of a service started by a timer will likely be inactive unless it is currently being triggered. If a timer gets out of sync, it may help to delete its stamp-* file in /var/lib/systemd/timers (or ~/.

Why does systemd not wait for the unit to finish?

Unless there are ordering dependencies in place, these services can/will be started in parallel. However, multi-user.target (and thus also graphical.target) are not finished until the rc.service finishes. That is why graphical.target is listed as “dead” for 1000 seconds.

When to start a service in systemd [ solved ]?

Services can be started in different ways, as configured with Type=. This determines when a service is considered “started” (or when the service’s start-up is considered finished). When a service reaches this state (some time after being started), units that are supposed to start After= this service will be started (and no sooner).

Unless there are ordering dependencies in place, these services can/will be started in parallel.
