hello,

i need to create a liveOS DVD with some unique requirements:

1) the root file system will be mounted directly off the DVD in read-only mode
2) i want to use in-memory disk for only /etc and /var for temporary 
non-persistent read-write

i have practiced using the livecd-creator tool to build a 
fedora-live-workstation and centos-7-livecd as a way to get familiar with the 
tool. it seems to me that the type of changes I want to make above, are not 
done in the kickstart %post section, so I assume it is done as part of the 
livecd-creator tool. I've read the README files, but I don't see a detailed 
description of how the root file system is configured to mount for the LiveOS. 
Looking over the steps described in the README, I *think* I need to better 
understand the following steps:

> Creates a live CD specific initramfs that matches the installed kernel
> Configures the boot loader

Is this the right direction to figure how to accomplish my above stated goals? 
If not, please help redirect me. If so, please help me understand those steps 
in more detail and how I can modify them to suite my needs. 

thanks in advance...
