Hello!
I am a not-so-experienced programmer and I started a personal project
which requires a deep understanding of the OpenBSD kernel - no, I am not
going to fork another BSD style operating system. I wonder if there is
documentation describing the kernel, other that the comments in the
source. For a start, I am reading Andrew Tanenbaum's "Modern Operating
Systems", 2nd edition and trying to follow the code in the kernel
source, starting with sys/kern/init_main.c
Is this a wrong approach? Do you have other suggestions? I know there's
no easy way and I am not looking for one, all I want is a starting point.

You don't mention what you had in mind so it is hard to point at anything.
"The Design and Implementation of the 4.4 BSD Operating System" by
McKusick and friends is likely to be more relevant for implementation
details, Tanebaum's book is more high level theory.
Well, I want to be able to write software which should run in kernel
mode and/or modify the kernel. Basically, I'm just like a college
student taking an operating systems course and using OpenBSD as an example.
