Comment 31 for bug 1285312

After manually updating to grub2 (the grub-pc package) and removing legacy grub, I installed the proposed mdadm on my development trusty system. I haven't looked at the SRU verification tests yet. I realise the cryptsetup warning is not directly related to mdadm, but sdb is the second disk in my soft raid array and I don't have ANY encrypted volumes. This would make me nervous about upgrading my production system! Here is the console log:
