  ---Problem Description---
  Currently syslog is getting flooded with below log messages ..
  Sep 25 03:16:41 ubuntu1710 systemd-udevd[2654]: Process '/bin/touch /run/run.vpdd
  update' failed with exit code 127.

  This is on UBuntu 17.10 latest build.. 
   
  ---uname output---
  Linux ubuntu1710 4.12.0-11-generic #12-Ubuntu SMP Fri Aug 11 12:23:06 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux
   
  Machine Type = ZZ-L 
    
  ---Steps to Reproduce---
   I have seen these messages logged more often when we do any hotplug operations.. ex. cpu hotplug..

  Ok. .this is the continuation of LTC #144627 / Launchpad #1682774.

  As suggested in that bug, we did change udev script to create
  temporary file under /run and that patch is available in ubuntu 17.10.

  Looks like this is udev script issue. If I modify systemd-udevd like
  below it works fine.

  I've limited udev knowledge. I don't know if you have any other better
  solution to this issue.
