Hmmmm .... there in no /netbsd on the system now. There are 2 kernels 
under /boot, kernel.img & kernel7.img (straight off of rpi.gzimg file I 
downloaded a few days ago, no mods by me) .... I also don't have a 
monitor hooked up now, did when it was back in my work room, so I can't 
choose a kernel if I wanted to :-/ ....

Sorta, this box is what I wrote out the original sd card with .... I do 
have the original image, & new familiarity w/ what I want to do, so if 
push comes to shove, I do have a longish fallback ....
