Woohoo! Congrats!
How do you run guix-daemon? (In the future it’d be great to perhaps
implement Linux namespaces on the Hurd in libc.)

OK.

That’s OK IMO.

Merging what you have—the earlier the better. :-)

Yup, sounds like a plan.

Dunno!
To me, the difficult bit with porting and bootstrapping work is making
sure that bootstrap.scm/commencement.scm/base.scm/cross-base.scm remain
maintainable. All this complexity adds up so we must spend time trying
to, for instance, minimize variation across platforms/OSes. Every line
of code and above all every conditional avoided in these files is a win
in the not-so-long term. That’d be my guideline as we merge it. :-)
Anyhow, thumbs up! I’m looking forward to merging it and having it
built on CI (we could offload to a Debian VM!)!
