- implement a dedicated setup mode for creating CA certificates that is triggered by the '-setup' command line flag - switch to YAML configuration for comment support and more human readable syntax. Format documentation is in docs/config.sample.yaml - move HSM related code to pkg/hsm - improve consistency checks in pkg/config
