The header still told readers to paste the raw GitHub URL, left over from
before we confirmed provider user-data fields run pasted/imported content
directly rather than fetching a URL.
IONOS's User Data field takes a Script Type choice (Cloud Config vs Shell
Script) and runs the pasted/imported content directly rather than fetching
a URL. Update the README to say so, add DEBIAN_FRONTEND=noninteractive for
genuine unattended cloud-init execution.
IONOS Cloud Server, DigitalOcean, and Hetzner all offer an "install
script"/user-data field that runs as root with no TTY while the image is
still provisioning, so bootstrap.sh's interactive tail can't run there.
cloud-init.sh clones the repo unattended and drops a one-shot
/etc/profile.d hook that launches the normal whiptail setup.sh wizard on
the first interactive login, then removes itself.
