[bug#41541] [PATCH 3/4] system: bare-hurd.tmpl: Add openssh client and service.

["Jan (janneke) Nieuwenhuizen" <janneke@gnu.org>]

This:

    ./pre-inst-env guix system disk-image --no-grafts --target=i586-pc-gnu \
        gnu/system/examples/bare-hurd.tmpl

now produces a VM image with functional ssh daemon that you may run like

    guix environment --ad-hoc qemu -- qemu-system-i386 -enable-kvm -m 512M \
     -device rtl8139,netdev=net0 -netdev user,id=net0,hostfwd=tcp:127.0.0.1:10022-:2222 \
     -snapshot -hda <the-image>

and use like

    ssh -p 10022 root@localhost
    guix build -e '(@@ (gnu packages commencement) gnu-make-boot0)'

or even (if you use --image-size=3G)

    guix build hello

* gnu/system/examples/bare-hurd.tmpl (%hurd-os)[packages]: Add openssh.
[services]: Add openssh-service.
