TODO
====

- proper documentation.
- install: move to /usr/local/share/hydra.
- bootless: always use first partition (like `/dev/sdb1`).
- ssh-config: hydra integration using a proxy command.
- init: version control in the superproject?
- metrics and alarms subsystem.
- deploy:
  - fqdn match via local config lookup.
  - fact collection.
  - lockfile.
  - keys and certs.
  - fix /etc/puppet permissions.
  - check hostname and required node configuration.
  - log applied version and date (in the node and so in the repo).
