The upstream kernel is able to create debian packages using 'make
deb-pkg' from the main makefiles. These .deb's postinst script have as single
functionality to run scripts in /etc/kernel/{pre,post}{inst,rm}.d/.

End of march this year there was some discussion in debian to make
bootloaders, initramfs-tools, etc. drop its installation scripts in that
directory and let them deal with making the new kernel bootable:

http://thread.gmane.org/gmane.linux.debian.devel.kernel/46349

I'm not sure if there have been concrete results of it, it seems to me
the thread died out.

Has this been discussed in Ubuntu as well? I feel it would make kernel
development and testing custom kernel much easier, if
scripts/package/builddeb via 'make deb-pkg' were properly integrated
into ubuntu.
