Kickstart within ISO - CentOS
 

Hi,

I am working on a software development project and I am facing a problem.

OS: CentOS5

Problem background:
I am working on a existing product. But now we have to upgrade the database (PostgreSQL) to a newer version. For that all the porting things are done. And now we are suppose to make a installation package. And they want it in ISO format. The upgrade should do -
1. backup the old db and uninstall the older version of PostgreSQL
2. replace the required binaries and install new DB.
3. restore the data.


Actual problem:
The existing ISO is designed only to upgrade the binaries. But since now we have backup/restore and install/uninstall the DB, we are stuck.
All I can see, using kickstart - putting necessary commands in pre and post scripts . But I am unable to find how to integrate the kickstart file inside the ISO.

Could someone please help me on this.

Googling showing only results for OS installation using kickstart. I don't need to install the OS but to patch an existing program using an ISO. Any help/pointer would be much appreciated.

TIA.

ps: we already have some script for building the iso.
ps: I am a beginner in Linux. All I have worked on - vi/grep/find etc. :)

Are you using something like cobbler? That will allow you to make an iso easily based upon profiles you can create.
