#===============================================================================
# felhom-bootstrap.sh — invoked by felhom-bootstrap.service, retried until host-install succeeds.
#
# ONE unit, TWO modes, decided by the env:
# DIRECT (env has FELHOM_CUSTOMER_ID + FELHOM_RETRIEVAL_PASSPHRASE) — the slice-A path, unchanged:
# fetch felhom-host-install.sh from the PUBLIC channel -> run it unattended with the
# customer's retrieval passphrase -> on rc 0 write the done-flag + disable + shred the env.
# PAIRING (R-21 slice C — the GENERIC secret-free ISO, no customer-id/passphrase in the env):
# register this box as an UNCLAIMED appliance at the hub (uuid + MAC set + SSH host keys +
# hw), receive a one-per-registration APPLIANCE TOKEN (0600), then POLL for the operator's
# bind. ONE delivery hands over customer-id + retrieval passphrase; the bootstrap WRITES
# them into the env (0600) and FALLS THROUGH to the DIRECT path — so every later retry is a
# plain direct install (the delivery is one-shot; the box must not depend on re-fetching it).
#
# The PAIRING wait polls INSIDE this script (v1.21.0, R-33). It used to be systemd's
# Restart=on-failure/RestartSec=30 — one poll per invocation, exiting non-zero until the bind landed.
# That worked, but every 30s systemd printed `Failed to start Felhom host bootstrap` on the physical
# console the CUSTOMER is watching: 52 FAILED lines in ~11 minutes during the 2026-07-18 rehearsal,
# while nothing was wrong (the box was correctly waiting to be bound). Waiting is not failing, so it
# must not be reported as failure. The unit now stays in `activating` and the loop sleeps between
# polls; the unit's Restart= machinery is kept for the DIRECT path and for genuine crashes.
# REQUIRES TimeoutStartSec=infinity in the unit — a Type=oneshot ExecStart is otherwise killed at
# DefaultTimeoutStartSec (90s), which would silently reintroduce the restart spam.
#
# Retry-vs-resume (source-verified, encoded ONCE): felhom-host-install.sh v1.11.3 makes --resume safe
# — its producer steps re-run every pass. FIRST direct attempt is plain; any later attempt that finds
# the install state file adds --resume. State file: /var/lib/felhom-install/state.json.
#
# R-59/R-60 (v1.24.0) — the FIRST-BOOT NETWORK GATE runs before mode dispatch: if the hub is
# unreachable, the box refuses to wait silently. It diagnoses (physical-NIC table, installer
# 192.168.100.2-fallback signature), SWEEPS the NICs while no install attempt has begun (re-point
# vmbr0 -> bounded DHCP -> hub probe; mechanics + bounds measured in
# documentation/audits/SPIKE-firstboot-nic-sweep-2026-07-22.md), and otherwise paints a legible
# Hungarian screen on the console and retries every minute — the unit stays `activating` and never
# exits non-zero while waiting (the v1.21.0 lesson: waiting is not failing).
#
# NOT production-generic: this is the R-21 bare-metal first-boot bootstrap. It does NOT modify
# felhom-host-install.sh; it only invokes it.
#===============================================================================
# Deliberately NOT `set -e`: we must capture exit codes and exit on our own terms.
