base.yml set AUTO_UPDATE=1 but never forwarded it to harden-ssh.sh (which defaults to 0), so base hosts never actually scheduled daily updates despite the config implying they did. Auto-update is intentionally bastion-only for now — jumphost.yml / harden-jumphost.sh enable it by default, and base (container) hosts will get a dedicated docker-image updater later — so remove the knob entirely rather than wire it through. No behavior change. Also drop cloud-init/base.yml from the README "Daily updates" line that claimed it takes AUTO_UPDATE=1.

# Generic base-host bootstrap -- Alpine, Debian, or Alma Linux.
|
|
#
|
|
# On first boot this:
|
|
# 1. Installs prerequisites (bash, git, curl) for whichever distro this is.
|
|
# 2. Clones this repo to /opt/automations.
|
|
# 3. Sets the hostname per the Network Domain Name Schema and installs the
|
|
# shared MOTD banner (scripts/setup-host.sh).
|
|
# 4. Seeds root's authorized_keys from globals/ (URL-preferred).
|
|
# 5. Applies SSH hardening: key-only auth, post-quantum KEX, sshguard
|
|
# (scripts/harden-ssh.sh).
|
|
#
|
|
# Fill in REPO_URL, HOST, and the other values, then paste as instance
|
|
# user-data. For a bastion host use jumphost.yml instead.
|
|
#
|
|
# NOTE: harden-ssh.sh prints a freshly generated root private key to stdout,
|
|
# which lands in the cloud provider's console/serial log. Either capture it
|
|
# from there, or rely on the keys seeded from globals/ and ignore it.
