Sure, but it's a bit of an unusual case to say the least, and I'm not aware of dkms packages in Debian doing that (happy to stand corrected if that's not the case). So surely any out-of-distro dkms package doing that should just ensure they pull in the dependencies they need for it? Assuming it's even needed. As far as I understand, the point of vmlinux.h is that it gives the equivalent information generated from BTF. The issue is that pulling the headers package also pulls the image, initramfs and all that machinery. We are going to depend on the headers package in src:systemd from the next release to get the vmlinux.h, and pulling all that stuff too adds considerable weight to the build dependency installation job. -- Kind regards, Luca Boccassi
