With this change, we can now use LUKS and LVM over NBD. There are some decisions to be made regarding where we should get the fstype and fsoptions from (DHCP root vs rootfstype= etc), but the basic functionality is there.
This is an initial test suite for the NBD root. It does the basics, and needs to be extended to check more parts of the configuration.
