Hi, I just ran into this again and had a look around: The systemd tool kernel-install(8) is already installed and appears to be working just fine.
It's "add" mode copies debian's kernel/initrd to the esp and adds a boot loader entry, which boots just fine. It's "remove" mode cleans up the copied/created files from the "add" mode. It appears there're just a few trivial /etc/kernel/?.d wrapper scripts missing? Regards, Andre
