Each linked overlay gets a checkbox on the blueprint detail page that opts
its server.cfg in as exec server_overlay_<id>. The web app builds the
spec with {path, alias} per overlay and prepends exec server_overlay_<id>
lines to the blueprint config in lowest-overlay-first order. The host
stages those copies in the overlayfs upper layer before mounting (avoids
copy-up writes against a sandbox-uid file). A live preview block above the
Config textarea shows what gets auto-executed.
Schema:
- alembic 0007: BlueprintOverlay.expose_server_cfg BOOLEAN
Spec contract:
- l4d2host OverlayRef(path, alias?). load_spec accepts both bare-string
and {path, alias} entries.
Side effects folded in (same file in l4d2_facade):
- start_server auto-initializes; the manual Initialize step is no longer
needed before Start.
- initialize_server no longer runs blueprint builders — builds happen on
overlay save, not on every server Start.
