Bug#612402: similar issue affects /usr in Jessie

[Marc Ballarin]

Hi,

since Jessie will attempt to mount /usr in initramfs when using Systemd,
this issue has somewhat broadened in scope. See the merged bug 781661.

While I agree with the reasoning that UUID and LABEL are not correct for
LVM volumes, and had in fact all our systems changed, this issue will
still cause a system to be unable to boot after upgrading to Jessie.

Not sure if it should be fixed or if it is enough to give a loud warning
on upgrade.

Regards,
Marc
