Yes, NetBSD finds the root device, or rather, the UEFI boot selector finds it, 
though two or more USB sticks of the same brand and model may show identically, 
meaning a wild guess on my part which is the desired one.

But the root device as NetBSD finds tends to be at variance with /etc/fstab.

It seems DragonFly bootable USB always comes as /dev/da8, or is it /dev/da8s1?  
It looks like removable media in DragonFly start at number 8.

So I wish NetBSD bootable USB would always come out as sd0a in the non-GPT case.
