I'm totally for a -dbg kernel package with an unstripped kernel for
OProfile, as I use it quite frequently.
I wanted to use OProfile and get kernel stacks on Ubuntu Breezy, so
ended up recompiling the standard kernel for vmlinux. To be useful I
needed to turn on DEBUG_INFO and DEBUG_FRAME_POINTERS, and this gave me
a 25M vmlinux. I'd expect DEBUG_INFO could be always on as the symbols
would be stripped for the production kernel, but I don't think "normal"
kernels should have frame pointers.
If this is correct, then maybe the debug kernel should be just another
build with the debug options on, and no stripping.
