I think I understand the problem. Could you try the packages (version 0.122~a.test) from https://people.debian.org/~benh/packages/ ? The patch is below. Ben. --- Subject: [PATCH initramfs-tools] init: Validate the real init after devtmpfs is mounted under the real root Currently 'run-init -n' will fail if there's no static /dev/console on the real root. We have to run it after udev's init-bottom script has moved /dev to ${rootmnt}/dev.
