# Container-boot reconciliation of per-profile gateway s6 services.
#
# Runs as root after 01-hermes-setup (the stage2 hook) has chowned
# the volume and seeded $HERMES_HOME, but before s6-rc starts user
# services. /etc/cont-init.d/* scripts run in lexicographic order,
# so the `02-` prefix guarantees ordering.
#
# Service directories under /run/service/ live on tmpfs and are
# wiped on every container restart. Profile directories under
# $HERMES_HOME/profiles/ live on the persistent VOLUME. This script
# walks the persistent profiles, recreates the s6 service slots,
# and auto-starts only those whose last recorded state was
# `running` — see hermes_cli/container_boot.py.
#
# Phase 4 also needs hermes-user writes to /run/service/ (so the
# profile create/delete hooks can register/unregister at runtime),
# so we chown the scandir before invoking the reconciler. We
# additionally chown the s6-svscan control FIFO so the hermes user
# can send rescan signals via ``s6-svscanctl -a``; without this the
# entire runtime-registration path is inert under UID 10000 (the
# Python wrapper catches the resulting EACCES, prints a warning,
# and swallows the failure).
set -e

# Make the dynamic scandir hermes-writable. The directory itself
# starts root-owned by s6-overlay.

# / -an work for the hermes user. The FIFO is created by s6-svscan
# at PID-1 startup, so by the time this cont-init.d script runs it
# already exists. Both ``control`` and ``lock`` need to be writable
# for the various svscanctl operations; the directory itself stays
# root-owned (we only need to touch the two FIFOs/locks inside).
