30_runtime_blueprint.sh calls POST /templates/{id}/resolve with the
device_id from the server handshake and the template_id from the
Bereitstellungsvorlage selection, storing the resulting Runtime
Blueprint under /run/tuxflotte/runtime/.
40_backend.sh dispatches to backends/${backend_id}/backend.sh based on
the resolved backend_id and drives the backend_init/validate/
generate_config/launch/postinstall lifecycle from 06-backend-api.md.
backends/fedora/backend.sh implements that lifecycle for Fedora:
backend_generate_config() renders kickstart.tpl via envsubst using the
Runtime Blueprint's installation_directives and the device hostname,
embedding the resolved Merkmal blueprints as JSON for the (not yet
implemented) Provisioning Agent to apply later. Replaces the old
git-clone-based %post bootstrap. backend_launch()/backend_postinstall()
are Phase 1 stubs pending the live-ISO boot integration (see
platform-docs ADR-0003).
20_profile_selection.sh and 25_installation_confirm.sh still spoke the
old flat profile model (.profiles[], .profile.distribution,
.profile.installer.type) that the provisioning server no longer
returns - it now returns .templates[] with workspace/backend objects
(see provisioning-server's Merkmal/Blueprint/Bereitstellungsvorlage
migration). Both modules now read/write
/run/tuxflotte/assignment/template.json against the current
Bereitstellungsvorlage schema, matching 10-interactive-provisioning-flow.md.
