Browse Source 
While systemd based, start lvm2-monitor.service failed.

|Sep 21 05:37:34 qemux86-64 lvm[389]:   /var/lock: stat failed: No such
file or directory
|Sep 21 05:37:34 qemux86-64 systemd[1]: lvm2-monitor.service: Main
process exited, code=exited, status=5/NOTINSTALLED
...
The failure of lvm2-monitor.service caused reboot hung when disk
partion is lvm thin provision.

While starting lvm2-monitor.service, it reqires the existence of
locking dir "/var/lock" which is a symlink to "../run/lock" in oe-core,
and "/run" is created in "/etc/fstab" which have to be be after the
start of lvm2-monitor.service.

So tweak the locking dir to "/tmp/lock" and make sure the dir existence
(after tmp.mount).
