This repository contains a slightly different version of the standard WSL2 Kernel, compiled with Clang/LLVM using LTO/Polly optimizations, geared towards data workloads, and including the necessary kernel changes to properly run AppArmor and Snaps.
Important: do not use our build artifacts in production as they are automated builds used exclusively for debugging purposes. Only our releases are properly tested and even those could potentially bring you problems in mission critical deployments as we only test those kernels for our own purposes. So exercise caution and keep hacking!

If you discover an issue relating to our kernel build, please report it using our issue tracker and DO NOT REPORT IT UPSTREAM. If we find that the bug is directly related to Microsoft's upstream version, we'll relay it for you.
Even if our build is very workload specific, you can still ask us to include features using our issue tracker and we'll consider the possibility of including it. Please note that inclusions aren't guaranteed, but we'll do our best to accommodate other needs as we go.
Please refer to .github/workflows/ as our builds are automated using GitHub Actions.
We'll work on documenting the process directly in the .yml files, but for now the code
is the documentation.
We plan on offering an install script in the future to automatically download and configure our kernel builds for you, but for now please see the documentation on the .wslconfig configuration file for information on using a custom built kernel and check our wiki for our own installation instructions.
