dal-rescue-01 install procedure (team#41058)

editing capabilities are limited, it's actually pretty hard to get

there.

From there, SSH was setup and key was added. We had DHCP in the lab so

we just reused that IP configuration.

    service ssh restart

    cat > ~/.ssh/authorized_keys

    ...

Then the automated installer was fired:

    ./install -H root@192.168.0.145 \

              --fingerprint c4:1a:be:9d:e4:b9:32:19:c7:08:44:1e:59:c9:e3:a9 \

              --verbose \

              hetzner-robot \

              --fqdn=dal-rescue-01.torproject.org \

              --fai-disk-config=installer/disk-config/dal-rescue \

              --package-list=installer/packages \

              --post-scripts-dir=installer/post-scripts/ \

              --ipv4-address 192.168.0.45 \

              --ipv4-subnet 24 \

              --ipv4-gateway 192.168.0.1

Note that the `ipv4-*` parameters were not actually passed but should

be used for testing later installs next time.
