mdadm create allows you to specify a device as "missing", and mirrors
run fine that way, but I don't know how you get the installer to do it.
The SME server distro (a modified Centos) does that by default if you
only have one disk when you install so you can easily convert to raid
later - and it makes a lot of sense.
