about compiling linux and freebsd kernel


hey guys,

i want to learn about kernel of linux and freebsd. however, after compiling them for the last few weeks, sometimes the result made os not bootable. i suspect some linkages were broken for some reason. so, here is my question:
1. how can you guys backup and restore to the previous state of, maybe a few hours ago or a few days ago?
2. any suggestion on how to learn kernel more effectively? i have searched the web extensively on this subject. any suggestion is appreciated.

thanks

richard

here! this is a excellent book for linux kernel inside out:

http://www.wiley.com/WileyCDA/WileyT...scription.html

check this out at your nearest book store, if you are a die hard fan of linux/unix kernel and want to get into OS development then you should definitely give this book a read..

whenever i compile and install a new kernel and it gets broken then i
1: delete the corresponding files from /boot/ directory
2: remove its grub entry
3: delete the kernel source directory from /usr/src
and use the old kernel unless i decide to compile another/same kernel again

i hope this information will help you
