I was involved within project which will trace the kernel. I used ktrace but I could not get appropriate results about the files being opened. I don't see any of the boot files boot0-1 or 2 in the ktrace.out file. Where did they go? Is ktrace the best "trace suite" for freebsd kernel? What about going through source code .. Is it better to use Combination of Ecllipse/Qemu and FreeBSD Source tree? Does this method will provide us with someway to see how booting process invokes the kernel to memory ? Any help will be appreciated. Yours, Chris
