This has now come up a couple of times.  Unfortunately, changing it
makes things a lot more complicated.  Right now, I know that if I have a
LiveOS directory, that's the live image and that's what I have to warn
people about if we change.  If instead, it could be in any directory,
how does the boot loader bits get handled?  

So while this gets some of the simple bits, if this is something that's
worth supporting, I'd rather think about the whole picture.
1) Do we want to support this just off of USB-type media or on CDs also?
2) How do we want to namespace so that we can better support multiples
and have them identifiable?
3) How do we want to handle the boot-loader pieces if we have multiple
OS options on the same medium?

On this list is fine

There's definitely at least livecd-iso-to-disk.  Possibly some of the
install pieces, but I'd have to go double-check.  And also some things
in the livesys initscript.
