Cool, I’ll start looking.

Great that you took the time to test thoroughly.

‘nss-mdns’ passes, but intermittently fails in my experience, but it’s a
tough problem.

‘encrypted-root-os’ was committed by mistake and the code to make it
pass has not been committed yet.  :-)

Of all the system tests, only the 3 in (gnu tests install) really test
the ‘guix system’ command, which is what we’re interested in here.
