I've built and booted other kernels quite happily so I guess what
you are suggesting is possible.

This is a u10, running a -current from Sep 16.

I tried another GENERIC build, which worked fine, but now..

root device: wd1a
dump device (default wd1b): 
file system (default generic): 
root on wd1a dumps on wd1b     
root file system type: ffs
warning: no /dev/console  

then, I hit <enter> and..

RED State Exception

Anyone else seen similar on u5/10 with Sep 26 source?

Oh, that reminds me - why must I specify the root device on every
boot? Shouldn't it be passed from the prom to the kernel? I'm using:

	config          netbsd  root on ? type ?
