Description

At the moment the boot.cfg file will always point to /KS.CFG file in the *.iso. While this is very useful there is other possibilities for installation e.g. through PXE. In this case the content of the *.iso file could be hosted on HTTP or TFTP server and with the right configurations in the boot.cfg file we will get untended installation.

Use Case(s)

Install ESXi servers through network boot

Potential Configuration

Add option to specify the URL for ks.cfg file and configure boot.cfg to point to this URL.
