Roll-based artifact installation on device

Hi there,
while playing around with the mender client, I wondered: is there a build-in solution for role-based artifact installation, perhaps dependent on the private key the artifact was signed with? The use-case would be: only an artifact that is signed with a certain private key can perform rootfs updates, others must stick to application updates. The logic could be implemented into the update module itself, but I wondered if this is solved in another way.

There is nothing built into Mender for this but a custom update module could probably handle this.
