Thanks Martin, I removed the superfluous lines, enabled mdadm.conf as 
instructed and rebooted fine.

The system was cleanly installed a couple of months ago using the latest 
release candidate for the AMD64 Etch installer. I used it to configure 
RAID1, with LVM2 on top, and DMCrypt on top of that.

Thinking about it, the duplicates are likely my own fault. I was advised 
to backup my RAID config as shown below, but I guess the installer had 
already done this for me:

 cd /etc/mdadm
 echo 'DEVICE /dev/hd*[0-9] /dev/sd*[0-9]' > mdadm.conf
 mdadm --detail --scan >> mdadm.conf

Thanks again.

PS) Nice readme.
PPS) Sorry for accidental direct reply.
