Comment 13 for bug 784216

For the record, I don't think that the error message *causes* the boot failures. It is just that your boot failed, and this was the most noticeable error message you saw.

I *think* that the message is innocuous, and just needs to be quelled. There has been some work in oneiric to transition stuff from /var/run to this new /run directory, and my guess is that this message is just some left over sharp corner that needs sanded down.

Many boot failures don't print error messages of their own, in which case the only thing you'd see would be this (unrelated) error message. Don't assume the error message is the cause of the boot failure though.

For debugging boot problems, look in your dmesg and the tail end of other logs in /var/log for other error messages.
