What are you trying to do?
In order to compare exactly a running image with an image release from the output of multipass find, comparing the image_hash of both is the only way to do it exactly.

What's your proposed solution?
Luckily, the information is already in the multipassd-image-records.json file. Outputting it in multipass find the same way that multipass info example does would be great.

Additional context
I'm making a Terraform plugin provider for multipass, and this feature would enable me to compare desired state vs current state exactly.
