+  * Remove partition device nodes of individual paths (for LVM on multipath) (LP: #1540401)
+    - debian/multipath-tools.dm-mpath-lvm.udev: udev rule for that.
+    - debian/initramfs/hooks: copy the udev rule and partx to the initramfs.
+    - debian/initramfs/init-top: load the dm-multipath module for 'multipath -c'.
+    - debian/rules: install the udev rule and init-top.
