Add these two hooks to /etc/pacman.d/hooks/ and systemd-boot will be updated automatically with new enteries.

Prerequisites:

• bootctl install (no configuration in necesarry!)
• mkdir /boot/$(cat /etc/machine-id) (needed for kernel-install to work, see the official documentation)

Other configuration requirements:

• None

Conflicts:

• Should not be used at the same time as a hook to generate a new dracut image on update, my hook is all you need

"Problems":

• Images are not placed in /boot/, kernel + initrd goes to /boot/$MACHINE-ID/$KVER/{vmlinuz,initrd}
