I have slightly cleaned-up a patch by Manolis so that I can run

    sudo ./pre-inst-env guix-daemon --disable-chroot --build-users-group=guixbuild &

This and other useful recipes I have noted in my scratchbook on the Hurd

   https://gitlab.com/janneke/guix/-/blob/wip-hurd-system/THE-HURD

I briefly looked at more work-in-progress daemon patches by Manolis, but
stopped when I found that it needs [t]his "new" libhurdutils library...
@Manolis?

Yes, that would be awesome!
