Sounds like that's actually their plan for the first pass (reading their papers now):
> While the DBMS engine will need some basic resource management functionality to bootstrap its execution, this could be done over a cluster of servers running current OSs, and eventually bootstrapped over the new DBOS.
Yeah, and TBH this is not a good reason to forge up a completely new OS. Even though the idea itself will surely improve performance, the immatureness alone will likely offset the benefits. It'll need years of improvements and tuning, which directly translates to $$$. Worse, normal people will not test the new OS for free, which is how things worked for Linux.
This was my first thought, and probably should be the first pass IMO. If they have to implement an entire novel OS to support this it will never be anything beyond a lab experiment.
