Sounds good.

A couple of quick questions/observations.  Does this cope in a sensible
way if, for whatever reason, the chosen daemon isn't present?

How hard would it be to add the 3rd option, stub-cxenstored into this
mix?  It is just one other key in xencommons to tweak.

SUPPORT.md doesn't appear to make any statements about the disposition
of xenstoreds, but stub-cxenstored is used by at least two major
downstreams so is obviously has security support in practice, and ought
to be tested.
