Restructure around a single entry point (automations.sh) with a Gum wizard and a self-extracting bundle for repo-less installs. Add scripts/oslib.sh so the provisioning scripts (setup-host, harden-ssh, harden-jumphost, sshuser) run on Alpine/Debian/Alma; seed root keys from globals/. - ntfy SSH-login alerts (user, source IP, key, region, jump target) via pam_exec - daily auto-updates with AUTO_REBOOT=idle (reboots only when no SSH active) and opt-in Alpine stable-branch upgrades - generic + per-deployment cloud-init; Gitea release workflow on tag - README/LICENSE/.gitignore/.gitattributes (force LF); repo URLs -> Gitea

# Jump-host (bastion) bootstrap -- Alpine, Debian, or Alma Linux.

#
|
|
# Same base steps as base.yml, but applies the bastion hardening
|
|
# (scripts/harden-jumphost.sh) instead of plain SSH hardening:
|
|
# - ssh-admins : full shell for maintenance
|
|
# - ssh-jumpers : ProxyJump only, to the JUMP_TARGETS whitelist
|
|
#
|
|
# Fill in REPO_URL, HOST, and JUMP_TARGETS, then paste as instance user-data.
|
|
# Add jumper/admin users afterwards with the installed `sshuser` tool.
|
|
#
|
|
# NOTE: harden-jumphost.sh prints a freshly generated root private key to
|
|
# stdout (-> the cloud console/serial log). Capture it there, or rely on the
|
|
# keys seeded from globals/ and ignore it.
