Currently the assisted-service uses the "nmstatect"l command with the gen-code option to generate NetworkManager files from manifests - https://github.com/openshift/assisted-service/blob/master/pkg/staticnetworkconfig/generator.go#L121.

When fleeting integrates with the the staticnteworkconfig pkg it must bring in the nmstate pkg to get this command. This is not desireable, it would be better if https://github.com/nmstate/nmstate was used to run the gc command.

Currently however https://github.com/nmstate/nmstate doesn't have a Go option to run gc (it can just get and set the NM config). This should be added soon and when it is assisted-service should be updated to use github.com/nmstate instead of "nmstatectl gc"
