[Bug 817114] Re: Oneiric network install fails with "mount: mounting /dev on /target/dev/ failed: Invalid argument"

[Jacob Strauss]

I see the exact same behavior.  Should /dev have its own partition?  I
tried a few bind mounts from the shell and all the ones I tried returned
EINVAL when the source was under /, and worked if they were elsewhere.
