OpenBSD Kernel Hacker's Guide ?

[CNL OpenBSD Miscellany List <openbsd-misc_(_at_)_lists_(_dot_)_ece_(_dot_)_iisc_(_dot_)_ernet_(_dot_)_in>]

Greetings!

	Is there an OpenBSD Kernel Hackers Guide?
	If yes, please let me know where I can access it.
	If not, please let me know where I can find documents
		that might help me.

	I could not locate in the OpenBSD Miscellanea Mailing
	List Archive.

	I believe the search function at www.sigmasoft.com does 
	not work. Did not find any match for query "openbsd."

	Thanks.
