Thanks for your reply! :)
(almost missed it as you replied only to the list ;-) )

For the latest mainline version I needed to go through combination of 4.6+4.7 anyway and then 4.5.4/4.5.5 way spared me messing with the config and personally I found it much simpler this way.

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?

In the mean time I've written a small script for this, but editing debian/config/amd64/defines.toml seems like a much better way.

Editing debian/config/amd64/defines.toml works great: thanks! :)
I'll have a look at debian/salsa-ci.yml later, but signing is not critical for me.

I've left a few minor comments.


Many thanks for explaining all this! :)
