Failed to create pty - disabling logging for job

[Goswin von Brederlow]

I'm booting a freshly bootstraped Precise with nfs-root. For that to work I had to replace mountall so the system isn't 100% pristine. I'm also using a custom kernel and no initramfs. But I've added some debug outputs to /dev/console there to see if everything works:

So both /dev/ptmx is there and /dev/pts is mounted so from then on logging should work. But the errors persist.

Booting continues and at some point I get a shell:

And that is where I get stuck. Why does upstart need to be restarted to be able to open pseudo ptys?
Why doesn't it work right after /dev and /dev/pts are created by the mount-virtfs job?

Can I restart upstart as part of the mount-virtfs job?
