Hello there,

I was reading the document of this project, and, interestingly, I couldn't find any way to restart or start a service?
Any suggestions? Could you update your documents, please?

In [12]: m.Manager.EnableUnitFiles?
Signature: m.Manager.EnableUnitFiles(*args)
Docstring: <no docstring>
File:      ~/.local/lib/python3.8/site-packages/pystemd/base.py
Type:      method

This API asks for three parameters; neither name of these parameters nor the type of them is defined or documented anywhere!

Another suggestion, maybe it's better to accept a string from the user and convert it to bytes inside pystemd module.

Thanks

Having looked at the documentation again and after reading this StackOverflow answer, I think this is the correct way to start, stop and restart services:

with Unit(b'your-service.service') as service:
    service.Unit.Start('replace') # Start
    service.Unit.Stop('replace') # Stop
    service.Unit.Restart('replace') # Restart

Does anyone know how to start the service with sudo?

That is my question as well. I was hoping to eliminate the systemctl subprocess with pystemd in my user mode application (I need to restart a unit after changing a config file) but I don't see how to do it with this package or any other.

I got the following error when tried to start a service:

unit.Unit.Start(b'replace')

Someone knows what means?
