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. ** Description changed: Binary package hint: udev I upgraded from natty to oneiric, rebooted a couple times, and noticed this error message: - udevd[79]: error: runtime directory '/run/udev' not writable, for now + udevd[79]: error: runtime directory '/run/udev' not writable, for now falling back to '/dev/.udev' - I wasn't able to get logged in with the oneiric kernel, so booted the - natty kernel (which this bug report was filed with). Both kernels - showed the same error message. + I booted with a natty kernel and still saw the error, so am guessing + it's not being printed by the kernel. + + Although some people in the comments are having boot problems, I think + this error message isn't related to boot failures, it's just that it's + the only thing you see, so you assume it must relate to the failure. + But I see it with successful live environment boots as well.
