Comment (by anarcat):

 today, i did a new-machine-hetzner-robot process almost entirely
 automatically, using fabric, with the followign command:

 {{{
 ./install -H root at 88.99.194.57 --fingerprint
 0d:4a:c0:85:c4:e1:fe:03:15:e0:99:fe:7d:cc:34:f7 --verbose hetzner-robot
 fsn-node-05.torproject.org installer/disk-config/gnt-fsn-NVMe
 installer/packages installer/post-scripts/
 }}}

 the fingerprint was the ed25519 one provided by hetzner email.

 this is a major step in the automation work because we reviewed the way
 Fabric handles remote hosts SSH keys (it doesn't, ouch), and worked around
 the problems found. we especially were able to add the `--fingerprint`
 argument *fairly* easily once I understood the internal mechanics of
 Paramiko (which wasn't quite obvious).

 the next step of this process is to finish converting the common trunk,
 new-machine, into fabric, so that (e.g.) puppet procedures are fully
 automated.

 but i can believe this can wait until the next server. doing this install
 took about a day because of the automation, so we shouldn't burn too much
 work credit on that...
