I was using this feature successfuly with 11.04 alternate. Right now I decided to upgrade to 12.04 LTS. It was frustrating to see that this is not working. I've then checked 12.10 and it's also not working.'
There was some other bug report
https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/728435
that stated that the problem was in mdadm package (not initramfs-tools). And it has been fixed. But apparently this is not the case.
