Sorry to sound basic, if I upgrade the kernel to v4 will
that mean
that I'm running version 4 of NetBSD?
In theory this shouldn't change the way my machine works,
it'll just
be running a newer kernel?
What worries me is if I compile a poo kernel and am unable
to get
back into the os to put the old image back.
What are the Qube specific switches and configurations used
to do
this?
I think I'm going to need some hand hloding through this or
I may
cry.
