That seems like a bug. OUTPUT_DIR should default to unset which would 
cause the internal KV_OUT_DIR to be set to KV_DIR.  However I can see 
from the code that's not the case, and it's not clear why.

Relying on "uname -r" or /proc/config.gz is still something we should 
avoid (unless user configured, perhaps, or in very exceptional 
circumstances) however it looks like this isn't a change that you are 
proposing.

Thanks for working on this. It's a sensitive area so please take care 
and help people pick up the pieces. If you are really motivated, it 
might be worth rethinking the whole separate output directory 
implementation.
