The `rauc install` calls the CLI in client mode.

However, the config is read and evaluated by the service.
Thus a `rauc install --config` ist meaningless for the service that performs the actual installation.

One exception is when compiling RAUC in non-service mode (without D-Bus).

What would work instead is stopping the rauc service and using

   rauc service --config ..

when restarting.


Could you point out your use case for using 2 different system.conf's here?

I bet there is a valid solution using only one system.conf.



Best regards, Enrico
