I am not sure because I don't have time to look up policy and I am on somebody else's computer, but since this makes my system _entirely_ unbootable unless I am manually finding a rescue disk and manually setting up the lvm to then rebuild the initrd, shouldn't this be an RC bug?
Important seems an understatement. Best, David P.S.: I hope this doesn't come across as angry. You are doing a great job on the seamless integration of lvm and cryptsetup.
