Title:
  Don't modify /run/run.vupdate unnecessarily

Status in The Ubuntu-power-systems project:
  Fix Committed
Status in libvpd package in Ubuntu:
  Fix Released
Status in libvpd source package in Focal:
  Fix Committed
Status in libvpd source package in Groovy:
  Fix Released

Bug description:
  This section is for Focal SRU purpose

  [Impact]

  A udev script is getting triggered whenever there is a change in
  sysfs. All is does is "/bin/touch /run/run.vpdupdate".

  Script was generic and used to trigger whenever there is any change in /sys/devices/ node.
  On large system it resulted in calling udev script number of times during boot and impacted on boot time performance.

  [Test Case]
  It is unfortunately difficult to reproduce this problem with the proper hardware setup so IBM will very that the new udev script is in place and acting as expected and that /run/run.vupdate isn't modified unnecessarily.

  [Regression Potential] 
  Even if unlikely a regression potential would be to prevent the system to boot.
