Re: kernel hacking
for the kernel sections in there man release man crash that pretty much gives you what that tells you. Neither of which tells you how to do kernel hacking. Start reading code and understanding it. 2009/12/10 Robert Yuri robert.yu...@gmail.com: which the best way to learn about OpenBSD kernel ? I found a bunch of docs from FreeBSD site such as developer's handbook at http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/ , there any same that for openbsd ? thanks, ry

So unless there is a good reason not to choose '1' for this purpose, I'd love to see a new diff from Ted. Being the same is a burden. You should go read the original top source code. making the key the same when we have a chance to is not a burden. Somebody forgot to provide much needed beer for the one (of many) nights that Theo spent reading Al Cahalan's re-write...(and others, but I don't have beer either.) top(1) and ps(1) have a long history. And not to mention Baggage... But having some consistency would be good. It bugs me when I shift from SYSV to oBSD and type 'ps-ef'. _ Eligible CDN College University students can upgrade to Windows 7 before Jan 3 for only $39.99.

Absolutely: $ pwd /usr/src/sys/kern $ wc -l * | tail -n 1 64300 total It's going to take you many nights just to *read* it. Not to mention the namecache-induced vomit breaks.

There are man pages for the people who want to know *what* the kernel does (or is supposed to do). But if you want to know *how*, presumably to change it, the source is the definitive guide. It is, by definition, up to date and always accurate. And you can't change things without changing the source, so you'll have to get into it eventually. There are several books listed on the website about other kernels. The details, but the concepts and principles don't. It's a tossup between the BSD book and the dinosaur book. The BSD book was specific, but it's quite old now, so it can be hard to know what's correct and what's not. The dinosaur book takes a different approach, and while it's not tuned just for one OS, I think it does a better job of separating concept from implementation, letting you pick up the details from the source.

The latter one details the MINIX system, though. Maybe others in here can chime in and come up with more recommendations.

Re: kernel hacking
That book is very relevant. Modern really means add more shit.
