In our setup the rootfs is ro NFS. It only becomes rw when combined with the tmpfs using AUFS. In this case we don't unmount the rootfs as it unnecessary. In Gentoo in /etc/conf.d/net you can define a predown() function that can be used to detect which network interface cannot be downed during a shutdown. This is useful when PXE booting as shutting down the PXE interface will cause the system to hang. Using the predown() we can detect if the rootfs is using AUFS and NFS and choose to keep the interface up so the system can gracefully shutdown or reboot.
