Amazing!


On foreign distro, I have missed how to setup the “childhurd“.  The
“guix system” is still a bit mysterious to me…


Using this command line (from gnu/system/examples/bare-hurd.tmpl):

    guix environment --ad-hoc qemu \
         -- qemu-system-i386 -enable-kvm -m 512  \
          -device rtl8139,netdev=net0 -netdev user,id=net0,hostfwd=tcp:127.0.0.1:10022-:2222 \
         -snapshot -hda \
         $(guix system disk-image -t hurd-raw bare-hurd.tmpl)

it is telling me that the ’ssh’ service is not started.  Therefore,

    ssh -p 10022 root@localhost
    ssh: connect to host localhost port 10022: Connection refused

What do I miss?


Then,

    login> login root RET RET
    root@guixygnu ~# $(guix build hello)/bin/hello

downloads, builds, and displays as expected “Hello, world!”. \o/


Last, I am confused:

   debian$ guix build hello --target=586-pc-gnu hello
   /gnu/store/09sz4qsqp3zgnbaxhzppspaxihwmfzll-hello-2.10

   root@guixygnu ~# guix build hello
   /gnu/store/<other-hash>-hello-2.10

What do I miss?


(Sorry for these naive questions.)


Thank you!  All is really neat!

All the best,
