Yes, thinking about this more, I think this is true.

Note we have to add it as the last drive anyway (since everyone
assumes the first drive added is /dev/sda).  Which means it doesn't
have a fixed name, so we have to pass the name in as a kernel command
line parameter, so the small initrd knows what to mount.

Matt has also mentioned using udev to rename devices, and also that
this might be a good time to add some swap.
