Strange, when I tried it here the allno.config had to be in the source directory. (Which I considered a bug.) Today I've been specifying the environment variable explicitly, to by pass the whole issue. > Anyhoo, stock -rc1 builds and runs fine here with that config. Here it boots up to a prompt, and I can type stuff at that prompt even, but if I try to do anything like whoami or ls, it dies. I could try to narrow down which syscall it's dying on, if you like.
