2.4.20 kernel install on red hat

i was hoping someone would give me some advise about kernel updates. rpm vs installing from source in redhat specifically. i have been just updating my system with red hats system update for my kernel. is there any noticeable difference if any at all by installing from source for the kernel? should i just stick to using the rpm's or should i attempt to install from source on my system this time around?

also i noticed in the read me files that come with the kernek source that i can configure my p4 system either as a i386 or i686. from what i can tell all rpm's from redhat for kernels are i386. slap me if im wrong . is there any benefit at all to configuring for i686. (i just know I'm sticking my for in my mouth right now )

thanks for any advise,

Er...>>slap!<< Just kidding!

Unless there is some functionality you absolutely gotta have and you know that you'll find it only in a later kernet (e.g., 2.4.20) stick with the Redhat kernel. You can get a smaller kernel by building it yourself, but it is smaller not because of the cpu against which the compilation takes place, but because of functionality you discard. Unless memory is a real premium in your setup, there is no need.

To see what cpu your kernel is compiled for, do a

uname -p

If you are 386, you are not going to notice much (if you can notice at all) a change to 686 (the P4).
