[Bug 1479929] [NEW] multipath-tools missing wwids can cause paths to be ignored on boot

[Mathieu Trudel-Lapierre]

Public bug reported:

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.
