| - | Clone the git repo specified and in the email. A new directory linux-5.0.y gets created which contains the kernel sources. Starting out with the distribution configuration file is the safest approach for the very first kernel install on any system. You can do so by copying the configuration for your current kernel from /boot. Once this step is complete, it is time to compile the kernel, install the new kernel and run update-grub to add the new kernel to the grub menu. Now it is time to reboot the system to boot the newly installed kernel. | + | Clone the git repository specified and in the email.

I apply patches and use the same repo to be able to detect regressions. I save dmesg for the current rc to compare with the next rc.
