Kernel packaging and configuration for Sunlight Linux — the recipe and config that produce the distribution's kernel (the low-latency sunlight variant).

Status: early bootstrap. This repository is being seeded. It will hold the kernel package build recipe and the Sunlight Linux kernel config(s), tracking an upstream Linux release with a small, documented set of changes.

slkernel builds the Sunlight Linux kernel package: it pins an upstream Linux version, applies the Sunlight kernel configuration (a low-latency desktop profile), optionally applies a small set of patches, and packages the result for installation.

• Config — the kernel .config / Kconfig fragments for Sunlight Linux.
• Packaging — the build recipe that fetches, configures, builds, and packages the kernel.

This repository does not vendor the Linux source tree; it references an upstream release.

• UEFI boot. Sunlight Linux is UEFI-only — the config must keep the options required to boot under UEFI (CONFIG_EFI*, efivars, the filesystems the installer creates, initramfs/block support).
• Low-latency profile. The Sunlight kernel is a low-latency build; the preemption-related options are deliberate, not incidental.
• Small, documented upstream delta. Track upstream closely; justify every config change and patch.

Implementation is in progress; the exact flow is TBD and recipe-driven (an xbps-src-style template, consistent with slpkgs, or a Makefile).

⚠️ A broken kernel config can produce an unbootable system. Always boot-test a built kernel in a VM (QEMU + OVMF for UEFI) before shipping it.

slkernel is one of the five projects in the Sunlight Linux tree, wired up via slmanifests:

repo init -u https://github.com/sunlightlinux/slmanifests.git -b main
repo sync -j4
# slkernel lands at kernel/
