Well, in that case...

Can somebody point me to good documentation on the kernel boot process 
(particularly what parts of the source tree makes the file 
/boot/kernel/kernel).  I'll then start looking at how to, cleanly and 
safely, provide a tunable boot verbosity (with the default being fully 

Assuming I eventually get that working I'll then look to the rc script side 
of things to seeing if, sensibly, similar functionality can be included.
