Bug Description

Booting a multipathed systems can fail in initramfs if the wwids file is not present and multipath-tools (with find_multipaths enabled) runs its detection before udev has completely detected all disk paths.

Solution would be to either copy wwids file on the initramfs image so that it's available on boot, or to make sure udev runs and finds all paths before running the multipath detection in scripts/local-top/multipath.

partman-multipath also needs to ship the wwids file in post-installations steps so that first boot will work.

This bug was fixed in the package multipath-tools - 0.5.0-7ubuntu3

---------------
multipath-tools (0.5.0-7ubuntu3) wily; urgency=medium

  * debian/initramfs/hooks: also copy wwids file on the installed system to
    ensure all paths come up on boot. (LP: #1479929)
