Subject: [PATCH] units: fix BindsTo= logic when applied relative to services
|
|
with Type=oneshot
|

|
Start jobs for Type=oneshot units are successful when the unit state
|
|
transition activating → inactive took place. In such a case all units
|
|
that BindsTo= on it previously would continue to run, even though the unit
|
|
they dependet on was actually already gone.
