Recent vanilla Kernels for Debian based distributions
Motivation
For me, Debian is the obvious choice for a server. But sometimes I need a more recent kernel. As I am lazy, I do not want to build the kernel and shuffle around the deb-files on my machines, so this is where this repo comes in.
Kernel Configuration
I used the Debian kernel configuration found in /boot/config-* and imported
it using make oldconfig and used the default values offered.
A linux kernel also knows make deb-pkg as a target, so packaging is done in
a breeze.
Attention: This kernel is NOT signed.

Sponsors
A big thank you to https://packagecloud.io/ for providing me with repository hosting for those packages as it wouldn’t be possible for me to host the repository on my line here.
