Bug#781560: lvm2 errors on every boot: initramfs scripts expect dmeventd (jessie)

[Chris Bainbridge]

Package: lvm2
Version: 2.02.111-2.1
Severity: normal
Tags: patch

lvm2 init scripts call vgchange without --sysinit
resulting in errors on every boot:

        "/sbin/dmeventd stat failed no such file or directory"
        "/sbin/dmeventd stat failed no such file or directory"
        "... event registration failed: no such process"
        "...snapshot segment monitoring function failed"

because dmeventd is not in the initramfs

fix: replace --ignorelockingfailure with --sysinit

/usr/share/initramfs-tools/scripts/local-block/lvm2
