I followed the kernel handbook (chapter 4 mainly) and it generally went pretty smoothly and I posted a mini-howTo on Debian Forums: https://forums.debian.net/viewtopic.php?t=166381

It is much easier to use "make bindeb-pkg" for this, instead of the
Debian official packaging (section 4.2 in the handbook).

From what I understand, `linux-signed` / `linux-image-${VERSION}-amd64` is generated by Debusine based on `linux-image-amd64-signed-template`, so I was wondering if:

If so, is there an easy to use script or a `make` rule to generate these maintainer-scripts from these templates?

I have used this workaround myself recently, but this will likely stop
working in the near future.

If you actually want to sign the kernel images yourself, you can see how
to do that in done in debian/salsa-ci.yml.  Otherwise you should disable
signing of the image by editing debian/config/amd64/defines.toml and
regnerate debian/control before starting the build.

I will try to update the instructions in the kernel handbook soon.
