FWIW I’d suggest squashing it with the patch that adds the MongoDB
service, since they really go together.

Does it require that ‘os-release’ file?  If so, should the service add
it?  That would probably intrusive though, so it’s even better if
MongoDB does not require it.

If it’s easy to do through the CLI, it might be worth trying insert an
element and query it.

Leftover.

Otherwise LGTM, thank you!
