this is a very general topic indeed, but i just need to know how to upgrade my kernel from 2.4.20-8 to 2.4.20-18.9
before i do that, is it worth upgrading? (what will i benefit by upgrading) and what are some risks?
do i install it by logging on as root or by doing a "su" in terminal as a user? i will probably need each command explained, thx
