The microceph snap already has auto-connect to block-devices but in order to actually figure out what block device to interact with, we also need hardware-observe.
This should be pretty uncontroversial given that block-devices is generally a superset of much of that and far more dangerous.
The snap is available in the store currently (snap install microceph --edge).
The source for it is currently in a private repo at https://github.com/canonical/microceph (though I expect we’ll flip it public shortly).
The usual process is to require two +1 votes over the 1 week voting period - in this case, there has only been one vote, however since this is pretty uncontroversial and has gone for 2 weeks without anyone else adding their vote, I have just granted this with the single +1 vote.
If other @reviewers disagree can you please chime in and we can revert this.
