Re: Really small kernel
Thanks for all the answers,
In essence i want to keep the kernel small so that it boots up as fast
Plus the hardware is a 75mhz laptop with very little ram, i want to save
as much ram as i can for other programs, hence the need for a small
As far as modules are concerned, i was under the impression that the
kernel + modules would be bigger (size wise) then having everything
together in one.
Do using (or not using) modules make a difference to the total size when
loaded into ram?
