[systemd-devel] Dynamic priorities for service loading using systemd ...

Hi all,

hope that is the right forum to raise my question.

I'm trying to realize a kind of dynamic mandatory / lazy service scenario using systemd.

This means in details that services are either mandatory or lazy. Mandatory services are started first, once all man. services have been loaded, the lazy ones can be started. It should not occur that a lazy service starts before the last mandatory one has been started.

For a static scenario I would define a mandatory target.  For all lazy services I would add a Requires and After dependency to this target.

But in my case, I need a more dynamic scenario. The assignment of services to mandatory or lazy is not fixed. It can be changed while the system is running or in worst case early during boot up. To my understanding I must automatically adapt the .services files of the services to realize such a scenario which looks a bit complicated to me.

Does anyone know another prettier solution for that.

Thanks in advance for help!!

Best regards
