[Fedora-livecd-list] specifying kickstart file upon boot of liveCD

[Jon Steer]

We have several use cases for the liveCD/liveUSB.
Some of the use cases require that there is manual intervention after boot
up for configuring the system and application evironment . But we have at
least two use cases where both system and application configuration is done
post-boot with no manual intervention.

The no-manual intervention is a precanned configuration for known system
enviroments (like a QA lab or marketing demo) that turns the machine into an
appliance.

We have several applications on the box that all require (for example) the
same sql authentication. Rather than have the user type it once (or several
times) we use precanned setup scripts or puppet.

You are right, I can add an init.d/foo that looks at /proc/cmdline.  I just
thought that I'd try to reuse kickstart for that functionality. Kickstart
provided most of what I needed like network setup and authentication setup.

thanks,
jon
