Fwiw, I've been burned by building a debug kernel, only to have
removed the original compile-directory for that kernel by the time I
actually *needed* the debug symbols.  It's one thing if you're building
a debug kernel because you know you're going to spend the next hour
debugging some change.  It's another if you're building a debug kernel
because your machine might panic sometime in the next two or three
weeks.

I'm not sure this change was the best idea to address that, but some
change along these lines would be nice.  Or is there some other knob
which already exists and I simply don't know about?  I have my own
ways to deal with this, but I'm sure that I am not the only one who
has been burned by this (and I am *sure*, because I have friends who
have also been burnt by this).
