   OK, the fault was that I was missing an /etc/mdadm.conf.

   What *doesn't* work is to unpack the initramfs and plop one in (I tried 
copying over the mdadm.conf I found in my working initramfs to the failing 
new one, but that didn't help).  You *have* to have the /etc/mdadm.conf in 
your root drive when you come to generate the initramfs.


   The reason I think I'd managed to get a working initramfs before was that 
I had a test virgin install on another partition from when I first set the 
new PC up (before I copied across the root from my old PC), and I'd filched 
the initramfs from that virgin install when the copy didn't work.

   The virgin install had the requisite /etc/mdadm.conf, which I've now 
copied to my proper root partition, regenerated my initramfs, and 
everything's working OK.
