I don't want to sound too negative but you can't put at the same level
"mdbp-ssh" and "mdbp-sbuild". Your abstraction is going too far by trying
to include remote building IMO.
And while abstractions are nice, for debusine I need to know how each
implementation work to be able to answer questions like "can I build for
that distribution on this worker" (i.e. do I have the required chroots) ?
And here your current abstraction is hurting more than it helps.
So I'm afraid that mdbp is just not suited for the needs of debusine at
this point.
Also given that you want to include support of building across multiple
machines, I don't really understand why you select a command line API
as the interface to drive this all. It's just not a good fit. Having one
process drive all the machines via ssh is just fragile and not really
scalable. And it requires all the machines to be directly adressable. In
debusine, only the server needs a public IP, the workers connect to it.

We managed to live without this for years, we can wait a few more months.
But it's not up to me to tell you what to work on.

Thanks for your feedback indeed, it improved the initial design and will
avoid some rework in the future when we add the abstraction.
