This is not an ubuntu kernel. It is a custom kernel that we build on our
own (we just happen to build the kernels in ubuntu) and we use them in
our testing pipeline with a debian rootfs. FWIW, 5.4 kernels booted fine
with previous versions of systemd.

My expectation would be that debian's systemd would be able to boot the
machine even with a custom kernel.
