Totally possible. If you read through the livecd-tools code enough, you'll figure out what needs to be done (as a worst case if you can't inspire someone else to do the work for you). Basically livecd-tools does a chroot install of fedora, then modifies it a bit, then performs the final steps you mentioned to convert it to a livecd. It's simply a matter of replacing that first step with taking your existing system, and then probably discovering that because of how your existing system differs from the chroot installed system, you have to perform a few other tweaks. Then generalizing the solution to make it useful for other people.
As another point of reference, my currently dormant project at viros.org, does the same thing, but instead of a chroot install, does a network-kickstart install in a qemu virtualized system. (and then the subsequent stuff in a much lighter-weight qemu virtualized initrd-only appliance). I mention my project, because it should really drill in the fact that all we are doing in both cases is taking an otherwise normal installed system, 'doing some stuff', and then converting it into a livecd with the latter steps you mentioned. 'doing some stuff' roughly equating to turning it into a hardware agnostic OS installation. (and that has actually become a much smaller set of things over the years).
Good luck... I'd love to help you further, but all my time is now going to a paying job finally :)

Hello,
I'm new to the list so pardon me if I break any etiquette rules... it's not intentional. :-)
The description of the Live CD Creator application found on Fedora's website includes a section on the steps performed by livecd-creator (see
http://fedoraproject.org/wiki/FedoraLiveCD/LiveCDHowTo#head-275d791c27ecce33...
). My question is whether there is a way to build a live CD using a / (ext3) filesystem created by some other means. Basically I'd like to be able to perform the last three steps listed in the document referenced above:
- Creates a squashfs file system containing only the ext3 file (compression)
- Configures the boot loader
- Creates an iso9660 bootable CD
We have already built a system and have it working exactly the way we want it. Is there a way to take that filesystem, compress it, and build the CD without having to go through the system configuration, package selection, and all the custom configs at the end? We'd like to build a CD that has maximum flexibility for compatible hardware.
I appreciate any help that can be offered. Thanks.
Todd
