Yep, this is relatively straight-forward and we have all the tools
that are really needed to create the filesystem image that runs
between python-imgcreate/livecd-creator and the things built on top of
it.  (Note: I'd really like the whole AOS/JEOS nomenclature to go
away; it's an image just like any other image.  Maybe one of them is
minimal, maybe another is not.  There's nothing particularly
"appliance" about it)

This is basically what I gather

The ramdisk _should_ just be able to be a standard Fedora ramdisk.  If
not, we have a problem.  The whole custom fstab and module preloading
blah blah blah is a side-effect of the pretty poor way the stock
Amazon images are constructed without partitioning, etc.  All of our
standard system tools can bring up Xen guests and once it's booted, it
should look like a regular system.

Once we're just using standard things built by our standard tools,
this is straight-forward enough to automate :-)

I can also help testing and have real systems where I'm using the
ancient Fedora stuff in production on EC2 that I'd be happy to have
running on a newer Fedora :)
