Doesn't work for kernels newer than 6.13 if I recall correctly. Tried to install it last month. I'm running Garuda Arch, and kernel 6.15, even having the repository active completely borks pacman.
Edit: it's an active project, so keep an eye on it. Or install CatchyOS as it's now standard there.
Edit²: I'm going to have another stab at it, possibly fucked something up? Idk, I was following the instructions, and everything was fine until I added the Repos to pacman.
