Isses with no prompt install

Question:

Env:
  AIX 4.2
  RISC 590 (sever) and 390 (client)
  sysback 4.2.0.0

Problem:
  I created a full system backup remotely from the 390 to the 590
  I then appended another full system backup created on the 590 to
  the same tape.

  I setup for a no-prompt install, here are the values I used:

cat /tftpboot/mars.sbinfo

PLATFORM rs6k
SPOT /usr
SPOTSRV 9.19.145.161
SPOTGATE 9.19.145.161
INSTSRV 9.19.145.161
INSTGATE 9.19.145.161
INSTMODE noprompt
INSTPROG /usr/lpp/sysback/inst/sysinst_noprompt
CONSOLE /dev/lft0
VGOPT root
RESTDEV /dev/rmt1
BUSEQ 2
SBDEBUG=1

So what I am doing is restoring the 2nd full system backup which was 
created on the 590.  The scsi ids are the same between the two systems.
It did not asked me if I wanted to remove sysback and the network parameters.

I put the debug.out file in the /home/sysback directory

The backup I was restoring was a power backup, I am not sure if that
matters.

This is a no-prompt install, so it will not ask these questions.
Sysback will never be removed from the system and the network parameters
will also not be removed. I realize that this may pose a problem when
installing from a different image.

How do you think this should be handled? There are a few options:
1. Dont do anything, requiring the user to setup the "rmnet" post-install
   script if they want the network info removed (the way it is now).
2. Always remove the network parameters
3. Remove the old params and reapply the new params according to the
   network install client info (but what about the old routing tables,
   network params configured for other adapters, etc?)
4. Force a prompt even if in no-prompt mode
5. Add an extra option to the network install defaults setup for
   removal of network params and of sysback product (this list of
   setup options may be getting a bit long).

Meant to append, not close. Please respond.

Here are my ideas on this:

Force a prompt even if in no-prompt mode only if the backup was created
on a different system then what it is being restored to.

I would like to see in the future,   
Add an extra option to the network install defaults setup for
removal of network params and of sysback product

This could be added in later releases of the product.

Note that if we force the user into prompt mode that it will be
impossible to ever perform a no-prompt install unless installing onto
the original system. I think this defeats the purpose of a no-prompt
install. If we're going to add the option, its probably better to
do it now. This is not a big deal but will require testing.
Let me know if you have any other thoughts.

2 new optins added to the "Set Sysback install Defaults" option,
one for removing Sysback and one for removing the network
config at the end of the install. This may apply even if the
install is NOT no-prompt. The default is no for both. Please 
check these out to make sure they work as expected.
