Comment 2 for bug 38924

Hmm, the initramfs looks at the root path to determine what to start. So If your root is on evms, it will start evms, which starts as much of lvm as it needs. Its possible that the bug with udev being not in the evms pre-requisites would cause what you were seeing: can you confirm this being an issue with evms 2.5.4-5ubuntu4 ?
