This tool is really great! Thanks!
I've got a working x86_64 configuration. I've also made some other
changes that I think make the livecd-creator script a little more
pythonic and added some little features that interested me.
I think I'd like to add support for multiple targets on the same CD at
some point, so I added in some abstractions that might facilitate
that. I also made some tweaks to the exception handling.
Anyways, I've attached it here. The changes to livecd-creator were
big enough that it didn't make enough sense to submit a patch. If I
get a chance later I'll break the x86_64 support into its own patch.
I think I saw some messages about a git repository in the archives.
It wasn't mentioned on http://fedoraproject.org/wiki/FedoraLiveCD
though. Where's a good place to RTFM?
