Somewhat yes. It will definitely avoid install time delay.

On runtime whenever udev script trigger (like after reboot), we will
rerun vpdupdate and it will have delay... which is fine.

yes.

Title:
  lsvpd: Do not run vpdupdate during installation

Status in The Ubuntu-power-systems project:

Status in lsvpd package in Ubuntu:

  ---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.
