Are you by any chance booting a file that is not called "/netbsd"?

Most apps that do lookups in the kernel namespace look into the file
"/netbsd". I happened to find out that "feature" when I installed a
selfbuilt kernel and booted it manually with "boot
wd0a:netbsd.SELFBUILT". See for instance the -N option in ps(1)

I'm absolutely not sure if it is a side effect of using 1.4.1 binaries
with a 1.5 kernel (or the other way around). I didn't do such a thing


Replace bitbucket with anything else.
