    DRAFT: system: examples: Add devel-hurd.tmpl.
    
    Try something like
    
        ./pre-inst-env guix system disk-image --no-grafts --target=i586-pc-gnu \
            --keep-failed --image-size=5G gnu/system/examples/bare-hurd.tmpl
    
        # You may not want to use -snapshot and lose your build results
        cp /gnu/store/...disk-image devel.img
    
        # We need just a bit more memory
        guix environment --ad-hoc qemu -- qemu-system-i386 -enable-kvm -m 1G \
         -device rtl8139,netdev=net0 -netdev 
user,id=net0,hostfwd=tcp:127.0.0.1:10022-:2222
    
        ssh -p 10022 root@localhost
        GUIX_PROFILE=/run/current-system/bootstrap-profile
        . $GUIX_PROFILE/etc/profile
        guix build -e '(@@ (gnu packages commencement) gnu-make-boot0)'
    
    or even
    
        guix build hello
