@Natanox i use mastodon since 2017 and at this point, i casually test kernel patches and even maintain a #bcachefs kernel package on #nixos (well, not very active anymore, but my name is in the metadata 😁)

https://search.nixos.org/packages?channel=unstable&show=linuxKernel.kernels.linux_testing_bcachefs&from=0&size=50&sort=relevance&type=packages&query=linux_testing_bcachefs

but all this is very easy on nixos

this was my initial commit of the bcachefs package

https://github.com/NixOS/nixpkgs/commit/4134db36d021b4715bdf0f4e54caee6d1255ee5e

this is how to patch a kernel

(i was a linux admin, devops and software developer, so i might be biased when saying it's easy)
