to reproduce, boot a yakkety disk1.img. this is a uefi image, so it has multiple partitions.

sudo sh -c 'echo overlayroot=tmpfs > /etc/overlayroot.local.conf && reboot'

you'll see it hang. the reason i believe is the info written to /etc/fstab for the non-root mounts does not include workdir information.
