ClaudeandClaude Opus 5 7eadcdf9e8 Bootstrap tree for the media box Linux conversion
Autoinstall lays down a thin base (sshd, key, DHCP, Docker CE, /srv) and hands
off to this repo on first boot. Everything interesting stays in git so it is
reviewable and re-runnable, rather than frozen onto a USB nobody can diff.

Stages, all idempotent:
  00-preflight  asserts hardware/BIOS state, changes nothing. Catches a BIOS
                update having silently re-enabled Secure Boot, which would stop
                the NVIDIA DKMS module loading on a box with no keyboard.
  10-secrets    ADD-ONLY seeder for /srv/secrets/stacks.env. Never overwrites an
                existing key. Verified against a pre-populated file: existing
                values, unrelated keys, the operator tier and existing manifest
                lines all survive byte-for-byte; a second run is a no-op.
  20-cifs       the 8 shares Plex actually uses (Share is excluded, it is not a
                library root). \040 escaping, nofail + x-systemd.automount +
                _netdev. Managed-block rewrite verified not to duplicate or to
                drop the root fstab entry.
  30-nvidia     nvidia-driver-580 explicitly: 580 is the LAST branch supporting
                Pascal, and the -open modules need Turing+. Pins against newer
                branches. Not in late-commands because DKMS needs the installed
                kernel, not the installer's.
  40-shell-mcp  builds the native MCP locally for amd64; refuses to finish
                unless /sse returns 401 without a token.
  50-plex       run by hand: PLEX_CLAIM expires in 4 minutes. Refuses to start
                against missing mounts and disables autoEmptyTrash, which with
                read-write NAS credentials is the most dangerous default here.

shell-mcp was built on arm64 originally. It builds clean on amd64 (whole dep
tree resolves to prebuilt manylinux x86_64 wheels, no compiler needed), but
dependencies are now pinned - the original installed mcp/starlette/uvicorn
unpinned and starlette has since gone 1.x. Port moved to 8103 so NPM host 42
can simply be repointed, and the tool description now says media box rather
than arrsstack.

# 30-nvidia — NVIDIA driver + container toolkit for the GTX 1070
#
# WHY THIS IS NOT IN late-commands:
# The driver is a DKMS module. It must build against the kernel that is
# actually running on the installed system, with that kernel's headers, on a
# real boot. Building it inside the installer environment produces a module
# for the installer's kernel, which is not the kernel that boots.
#
# DRIVER BRANCH — this is the part that will bite later:
# The GTX 1070 is Pascal. NVIDIA's 580 branch is the LAST branch that supports
# Maxwell, Pascal and Volta; it is now a frozen legacy branch receiving
# security fixes only. There will be no 590 for this card. Two consequences:
# 1. We install nvidia-driver-580 explicitly. Never `ubuntu-drivers autoinstall`,
# which will happily pick a newer branch that does not support the card.
# 2. We install the PROPRIETARY module, not `-open`. The open kernel modules
# require Turing or newer. On Pascal they will not load at all.
#
# Secure Boot must be OFF (verified 2026-07-27). With it on, the DKMS module is
# unsigned as far as the firmware is concerned and requires interactive MOK
# enrollment at a physical console — on a box with no keyboard.
#
# Plex is targeted at Quick Sync, not NVENC, so this stage failing does NOT
# block Plex. It fails soft.
