I am building my custom kernel as an rpm package, but I would like also to generate a separate rpm package for my kernel. One that is similar to kernel-debuginfo and kernel-debuginfo-common from RH, or kernel-*-dbgsyms.deb from Debian-like distros.

I know this has been asked before. But I do that there were no real answers given that achieve the goal. And I believe that this should be an easy thing to do given that it how often it needs to be done.
