Build CachyOS Kernel 6.19.2 on Debian Forky (VENV)

 In general we follow https://news.itsfoss.com/cachyos-kernel-builder/

Start with Pre-installation step

$ sudo apt install build-essential bpftool 

and include /usr/sbin in system $PATH variable.

On Debian forky  installation of libdw-dev and build dependencies for libdw-dev steps are required to succeed with build CachyOS 6.19.2 Kernel on top of Debian Testing ( forky native kernel 6.18.9 )

$ sudo apt install libdw-dev

$  sudo apt-get build-dep libdw-dev

Proceed with cloning https://github.com/Nitrux/linux-cachyos-deb

$ git clone https://github.com/Nitrux/linux-cachyos-deb

$  cd linux-cachyos-deb

Script installs all required packages and pops up TUI dialog to configure kernel 6.19.2 and finally proceed with building of debian kernel packages.

$ ./cachy-kernel-deb

Install kernel via debian files been built and reboot into CachyOS Kernel 6.19.2

Cockpit VNC Console ( in detached state ) along with KVM Hypervisor functionality under CachyOS Kernel were tested on the top of the most recent state of Debian forky installed in virtual environment

/var directory was mounted on LVM separate volume to keep enough space for further kernels testing
