Aha.. so that's it. I've never been able to get /linuxrc to execute automagically. I wonder why /linuxrc executes on Art's system, but not on mine. I can call it whatever I want and it doesn't run unless I explicitly start it with init=whatever.
If it does execute though, that explains init complaining.. pid is going to be whatever comes after the last thread started (would be 8 here). It looks like you're only supposed to do setup things in magic filename /linuxrc and not exec /sbin/init from there.
In any case, it looks like renaming linuxrc to whatever.sh and booting with init=/whatever.sh instead will likely make init happy.
