multiple kernels

[Ravi Kumar Munnangi]

Hi Users,
 
  Iam currently using RedHat 8.0 (Linux-2.4.18-14).
  For some reasons I want to have Linux-2.2.17 also
  on my system.
  I can compile the new kernel but I want to skip the
configuration part. Because Iam new to linux Iam not
much confident of configuration process. Is there any
way to make use of already existing configuration on
Linux-2.4.18? Will this work?
  Please help me!

 Thanks,
ravikumar

you can copy the .config file from the previous kernel's tree to your
current kernel tree.

This is true, however, that doesn't mean it will work. There are a lot of 
differences between 2.2 and 2.4.

At very least you must run make oldconfig to bring things forward, and I'm not 
sure you can go backwards, though it might work.

But for all of that, you'll still have to answer lots of questions, and know 
your machine pretty well.

Why do you need the older kernel?

There might be incompatibilites with the rest of the system. I'd advise
against it.

Why, in any case?

No way.

Just go slowly, read up on each configuration option (there is on-line help
in the configurators, e.g. "make menuconfig"), try it out and tweak from
there. A more knowledgeable person by your side the first time is very
useful...

It might. The configuration changed quite a bit... again, I'd advise
against trying it if you don't know your way around (yet).

Good luck!
