How so, to what should the names be changed?

I presume you are referring to the hook of /scripts/init-bottom/ORDER to add
   iface eth0 inet manual
to /etc/network/interfaces.

This is critical, because if NetworkManager tries to initialize the network device, it will hang during boot (nbd-client isn't intelligent enough to reconnect, but thats a bug for another thread). Downing the network interface effectively unplugs the root block device.

I don't care how or where the hook is made---but somehow NetworkManager needs to be disabled for the session on that network interface.

How is this handled for NFS and CIFS root filesystems?
