-
-  [ Olivier Gayot ]
-  * Build ubuntu-server with multipath-tools-boot installed, so that the
-    multipath stack ends up present in the initramfs.
-    The LVM stack is already present in the initramfs of the installer. And
-    since kinetic, the /dev/mapper entries for LVM devices are created during
-    the initramfs phase. This is a problem when we have LVM on top of a
-    multipath disk because LVM ends up creating /dev/mapper entries out of
-    /dev/sdX (or /dev/sdXpY) devices, not out of /dev/mapper/mpatha as it
-    should. Adding the multipath stack in the initramfs gives multipath a
-    chance to take ownership of /dev/sdX (or /dev/sdXpY) devices before LVM
-    does (LP: #2080474).
