Thanks for the continued rants about Arch, systemd, and Linux; your
point has yet to sink in! :)
A bug report was filed more or less a year ago about make-kpkg's
kernel_headers target not creating the build and source symlinks (or
creating them incorrectly) but I can't find it at the moment.
You can force the build symlink to point at the "right" directory by copying
"/usr/share/kernel-package/examples/etc/kernel/postinst.d/force-build-link"
to
"/etc/kernel/postinst.d/force-build-link"
You could create a "force-source-link" script to do the same for the
source symlink if you're unhappy with the current make-kpkg default.
"make deb-pkg" creates the build symlink in the debbuild script but
doesn't create the source symlink.
