Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe backlight script adds Limine as a kernel-parameter backend. It locates and parses supported configuration files, edits Linux entries through the privileged action flow, and reports Limine status. The English and Dutch documentation now describes Limine support as early and untested. ChangesLimine backlight support

Merge Risk: 🔵 Low · up to Limine users whose configuration uses CRLF line endings will see enable and disable fail with a changed-on-disk error, and nothing is modified. The fix is small. Limine support is already labeled early and untested. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new integration changes boot-critical configuration with administrator authorization. It checks for stale contents and attempts rollback, but a failed restoration is followed by deletion of the saved recovery copy. Exposure is local to the machine; filesystem ownership and concurrent-write assumptions remain unverified. Retained concerns

It sets the kernel parameter through GRUB or through `rpm-ostree kargs`, whichever the system uses, and only enables the fix on a GA605WV. `disable` reverts what `enable` changed rather than just deleting it: an `acpi_backlight=` value it replaced, and a modprobe rule of your own that it moved aside, both come back.

Summary
The backlight fix did not configure kernel parameters for Limine. This adds Limine configuration support and documents that the new path is early and untested; it may be unstable or not work.
