Bug#560210: lvm2: Mounting root from an LVM on USB waits too late

[Stefan Monnier]

Package: lvm2
Version: 2.02.54-1
Severity: normal

All my machines use LVM for all partitions other than a small /boot
partition containsing the initramfs.  This usually works well, but
when I recently tried to boot one of my disks over USB I saw a problem:
the "rootdelay" waits for the device to appear, but too late,
because /usr/share/initramfs-tools/scripts/local-top/lvm2 is executed
before that, so I typically get the following sequence:

   ...
   LVM failed to find the root device (as well as the resume device)
   ...
   waiting rootdelay
   ...
   found sdb1 and sdb2
   ...timeout:
   not found root device /dev/mapper/Foo-Bar
