Yup!  Probably we’ll create /etc/childhurd/HOST for each VM, so we also
need to adjust <hurd-vm-configuration> accordingly, right?

(I realize that the current code will silently keep going if we forget
to put the secret files in place; IOW, the service config doesn’t show
the files we intended to push as secrets.  Oh well, we’ll see that
later.)

Yes, or maybe just change ‘systems’ in the Cuirass specs for
‘guix-master’, but then it’ll try to build everything for GNU/Hurd,
which doesn’t sound like a great idea for now.  Perhaps we can simply
add a separate jobset pulling from ‘master’ but building only for
i586-gnu and only the “core” package set?

LGTM, thanks!
