  git clone --single-branch --branch=linux-5.4.y https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
  cd linux
  cp /boot/config-`uname -r` .config
  yes '' | make oldconfig
  make -j `getconf _NPROCESSORS_ONLN` deb-pkg LOCALVERSION=-custom
  
secureboot muss deaktiviert werden, um custom-kernel zu booten, sonst kommt die Fehlermeldung "error: /boot/vmlinuz-x.x.x-custom has invalid signature"
