Does 'makeoptions DEBUG=-g' add any kind of performance hit or

No. It just means that a debug kernel is built in addition to the
normal kernel. The major benefit is that if you do get a panic,
you can debug it without needing to rebuild the kernel.


I've often thought that the default should be for this to be
on instead of off. Does anyone know why the current state is
so? I suppose it incurs a small amount of additional disc
space but the benefits are considerable for everyone involved.

Clarifying what I was getting at (it does default to on) I meant
that it has to be turned on with an option not turned off.

Dominic
