I thought about it more between yesterday and today, and it continues to
seem strange to me that we're doing "probing" here.  We don't probe to
guess where Guix is currently installed or etc to specify disks.  I
guess that's not the same thing, but...

Here's the concern: imagine that we want to be able to up-front do
something like "guix system build" before we even start spinning up
servers.  Does this block that direction?

Dave, your input appreciated on this one.

I'm not sure I want to block the patch series with my hand wringing, but
I do want to make sure we give it appropriate consideration.
