Enhancement: Added argument spec and assert role spec validation to the bootloader role. Also wrote tests for it found in tests/tests_invalid_input.

Reason: Because it is a good addition to the linux-system-roles project.

Result: Successfully added it and prepared tests for it. I used AI during this implementation.

    • Added comprehensive parameter specifications for bootloader configuration, including kernel settings, timeout, passwords, reboot behavior, fact gathering, and secure logging.
    • Added validation for bootloader parameters before configuration begins.
  • Bug Fixes

    • Invalid values now produce clearer, type-specific validation errors, including details about affected kernel entries and options.
  • Tests

    • Added coverage for invalid parameter types, unsupported values, missing settings, and malformed kernel options.

Changes

Adds an Ansible argument specification for bootloader parameters, runtime validation before configuration, and invalid-input tests for argument-spec and assertion failures.

Bootloader validation

Layer / File(s) Summary
Define bootloader parameter contracts
meta/argument_specs.yml
Defines bootloader_settings, kernel and option shapes, timeout, password, reboot, fact-gathering, and secure-logging parameters.
Validate parameters before configuration
tasks/assert_role_vars.yml, tasks/main.yml
Validates timeout, password, kernel entries, and option values before configuration tasks run.
Test rejected parameter values
tests/tests_invalid_input.yml
Tests argument-spec and runtime assertion failures, then clears test facts.

Merge Risk: 🟡 Moderate · up to 40448

The PR adds role argument validation, but entries missing kernel can still bypass validation on some execution paths, while the new invalid-input tests do not exercise the managed role path. These bounded correctness and test-fidelity issues should be fixed before merging.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject settings entries without kernel.

Line 36 skips this assertion when kernel is absent. On paths where argument specifications are not applied, the malformed entry reaches bootloader configuration without required-field validation. Assert that item.kernel is defined before checking its type.

Proposed fix
   ansible.builtin.assert:
     that:
-      - >-
-        item.kernel is string
-        or item.kernel is mapping
+      - item.kernel is defined
+      - item.kernel is string or item.kernel is mapping
     fail_msg: >-
       bootloader_settings[{{ idx }}].kernel must be a string
-      or dictionary, got {{ item.kernel | type_debug }}
+      or dictionary, got {{ item.kernel | default(none) | type_debug }}
   loop: "{{ bootloader_settings }}"
-  when: item.kernel is defined
