My kernel modifications are kept in ~/work/; other people like /usr/src/linux/* or similar, but it requires some level of root permissions to modify the directory much, and I try to do as little with root as possible. For compiling your changes, you can follow the directions as located in the Kernel HOWTO. It is exactly the same as compiling the mainline kernel. > 2) How to boot up my linux machine with new image. Hardware and system dependent. I think Red Hat uses grub these days, so a quick read of the Grub HOWTO is a good idea. I bet grub and its configuration file have manual pages -- man -k grub, and read the pages listed. > 3) If my new kernel image is not good enough for my > machine to come up, then what is the method to tell > linux machine to use some backup image incase... This depends on how badly you screwed up the kernel. :) If you just made little mistakes, grub or lilo will be able to keep backup kernel images. If you made big mistakes and yourr system isn't bootable with different kernel images, then you might wish to use a system such as mondo to restore your system from backup. Or keep your system changes in CVS or something like that. Have fun. :) Oh yeah, don't forget to browse the links from the kernelnewbies.org website. :) -- http://www.wirex.com/
