### Binary cache
I'm running a Hydra CI to build the kernels and push them to my Attic binary cache. You can see the build status here: <https://hydra.lantian.pub/jobset/lantian/nix-cachyos-kernel>
To use my binary cache, please add the following config:
```nix
{
nix.settings.substituters = [ "https://attic.xuyh0120.win/lantian" ];
nix.settings.trusted-public-keys = [ "lantian:EeAUQ+W+6r7EtwnmYjeVwx5kOGEBpjlBfPlzGlTNvHc=" ];
}
```
This repo also has [Garnix CI](https://garnix.io) set up, and should work as long as the total build time is below the free plan threshold:
```nix
{
nix.settings.substituters = [ "https://cache.garnix.io" ];
nix.settings.trusted-public-keys = [ "cache.garnix.io:CTFPyKSLcx5RMJKfLo5EEPUObbA78b0YQ2DTCJXqr9g=" ];

### Help! My kernel is failing to build!
In most cases, failing to build a kernel is caused by CachyOS not updating patches for the latest kernel version. (e.g. hardened 6.18 kernel as of 2025-12-12)
