Linux: Custom Kernels Trim Fat and Tune Performance

"A word of warning: while building a custom kernel isn't all that difficult, it is complex and time-consuming, and when you're all finished you might be the proud parent of a non-booting kernel. The good news is you can have as many do-overs as you want without hurting your system. Any Linux system can have any number of kernels and you can choose which one to boot to, so never delete old kernels until you're certain your new one works correctly. Your system will not try to boot to a new kernel until you explicitly configure it to do so, so it can't sneak up on you. So you can go on a wild spree and build and test a whole army of new kernels if you like."
