Problems with the /usr/lpp/sysback/scripts/install.post script

Question:

Env:
  AIX 4.2.1
  RISC J30
  sysback 4.1.4.1

Problem:
  Customer made changes to the /usr/lpp/sysback/scripts/install.post
  script.  Then the customer did a remote backup to a file image.

  The customer had a older /usr/lpp/sysback/scripts/install.post on
  the network boot server system, where she did a network boot from.

  Instead of using the install.post script from the backup created on the
  client, it used the install.post from the boot server where she did a 
  network boot from.

  
  It that how the install.post script should work?

  Which install.post script will take presidence over the others

  1. Customer Installation Diskette
  2. Backup image the client installed from
       scripts in the backup image in /usr/lpp/sysback/scripts
  3. Scripts on the network boot server
       scripts in /usr/lpp/sysback/scripts

As I understand it, there is an install.post program on the server and
on the client where the backup was made from. The client is booted from
the server, then restores from a backup on that server. When done the
install.post script on the SERVER gets executed, not  the one in the
backup image as expected.

I cant find any way that the install.post script on a server would
get exececuted on the client. The install.post script gets executed
after the restored /usr filesystem gets mounted over the /usr filesystem
from the server. The install.post diesnt get copied from the server
to the client, and I'm not sure that it should.

I did find where the restored install.post could override the install.post
from the diskette. This I plan to change, but is not the same problem
your customer is having.

Any more info you can give me? If you havent tested this, I can
plan to test this as I develop the recovery install process.

OK, I found where it gets copied from the server to the client.
Do you think a post-install script on the server should get
applied to all clients that install from it?? I'm thinking not,
but lets talk if you dont agree.

For now, I'm going to prevent the server copy from getting copied to
the client. This will prevent the restored copy from getting
overridden.. I'll also make sure the copy restored from diskette,
if any, overrides anything that gets restored.
