Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change keeps faster loading and libredirect disabling opt-in, preserving existing behavior by default. A bounded settings risk remains because persisted options can become contradictory, and switching container types can leave the faster-loading setting inaccessible; this is mergeable with explicit owner follow-up.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Keep the faster-loading switch enabled for non-Bionic containers.
disableLibredirect is a Bionic-only setting, but this condition ignores config.containerVariant. If a user enables it in Bionic and then changes the container to GLIBC, the flag remains persisted while its switch is hidden. The faster-loading switch then stays disabled even though faster external loading is available for that variant.
Make the condition variant-aware, or clear disableLibredirect when leaving Bionic.
Proposed fix

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
