Comment 8 for bug 1350416

Just to say that today I wanted to convert my trusty to utopic and it was a total desaster. In addition to what was mentioned above, there was no initrd for kernel 3.16 created, which led to a nice kernel panic when rebooting. BTRFS saved me, so I could roll back to the state before the update, sudo update-grub and will stay on trusty a while, probably checking the release upgrade first in a vm drawn from my current installation.
