• stores it as a Proxmox Template

Configurations

• haveged random number generator to speed up boot
• passwordless sudo for default user 'deploy' (name can be changed in build.conf)
• SSH public key installed for default user
• display IP and SSH fingerprint before console login
• generates new SSH host keys on first boot to avoid duplicates in cloned VMs
