ubuntu-autoinstall skillA

ubuntu-autoinstall is agent-read markdown (skill) from air-gapped/skills: Author, validate, and debug Ubuntu Server autoinstall configuration (the Subiquity installer's `autoinstall:` schema, version 1) for Ubuntu Server LTS 24.04 and 26.04, focused on unattended on-premise and air-gapped installs — identity, storage (LVM/direct/ZFS/encryption/RAID), apt mirror-selection + proxy + offline fallback, ssh, packages, kernel, late-commands/early-commands, and zero-touch delivery via a NoCloud seed. The `network:` block is netplan v2 (use the ubuntu-netplan skill); the `use.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add air-gapped/skills/ubuntu-autoinstall@git:20260614.900b4d1
Exact content
mdr add air-gapped/skills/ubuntu-autoinstall@sha256:8fe0204688426033

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
