Does this trade an install-time delay against a delay the first time the
user runs the command?

Or, since the udev rule sets the flag each time it's run, will there always
be a delay on the first run after each reboot, thus making the install-time
generation pointless?

  lsvpd: Do not run vpdupdate during installation

  ---Problem Description---
  Presently during installation we run `vpdupdate` command which generates vpd database. (see debian/postinst) .

  Its quite heavy weight process.  Also we have way to detect/rebuild
  database during runtime. Hence there is no need to run this command
  during installation.

  Lets remove it from installation script.
