Description

I mantain a WSL distribution at my company, and I want to include a custom distro-specific kernel.

Can you implement one of:
- make it possible to have distro-specific kernels,
- make it possible to read the kernel from a distro's rootfs at startup, or
- enable kexec support in the WSL kernel so that I can switch after boot?

Research direction

The issue names no files, tests, or entry points. Start by investigating WSL kernel startup and how distro configuration selects a kernel, then compare the feasibility of rootfs loading and kexec. Done means implementing one supported path for distro-specific kernels and validating that a custom kernel can be selected or switched.
