Launching Red Hat from within Altiris Linux Automation Environment

I spent a couple of days last week pulling my hair out trying to get our RHEL5 Linux build to install from within Altiris.
The most common approach uses the Altiris DOS Automation environment to configure GRUB4DOS which launches the RHEL5 kickstart installation on the next reboot.
I couldn’t get the Altiris DOS Automation environment to work (the shared drive mapping failed) and I couldn’t be arsed picking through our policies to fix it.
Another approach linked here, creates a custom PXE boot menu option that starts the RHEL5 install. I wouldn’t recommend this approach as it takes away the manual step of dropping a job on a computer object in DS to deploy server images. You know it would only be a matter of time before some butter fingered monkey starts rebuilding all your RHEL servers.
What I really wanted was to just launch the kick start install from within the Linux Automation environment ala the way you launch Windows in WinPE.
Thanks to viddect for pointing me in the right direction.
Hopefully this will save other linux n00bs a few headaches. I separated the different steps into multiple ‘Run Scripts’ tasks for error checking. I tried to combine them afterwards but they didn’t act the same. Who knows why. I have learnt not to ask too many questions of Altiris.
