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...
