Add the files that land in the image, organised as layered rootfs trees (base first, then the edition layer wins on conflict). - base: hardened kernel cmdline + sysctl, default-deny nftables, key-only ssh, persistent journald, module blacklist, no core dumps, snapshot timer units, motd. - server: Prometheus + auto-provisioned Grafana + Loki + promtail. - workstation: dev profile and desktop sysctl relaxations (perf, rootless containers). - cloud: cloud-init provisioning config.
