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).
How to ensure that there is a delay before a service is started?
So for example, to wait for 1 minute after boot-up before starting your foo.service, create a foo.timer file in the same directory with the contents: It is important that the service is disabled (so it doesn’t start at boot), and the timer enabled, for all this to work (thanks to user tride for this):
How are services started in parallel in systemd?
One of the features of systemd is that it starts services in parallel. Your graphical.target wants both multi-user.target and display-manager.service. multi-user.target wants this rc.service (and many other things probably). Unless there are ordering dependencies in place, these services can/will be started in parallel.
