Nope, it's going to require an explicit stage2=.  We're not going to go
off searching every disk on the system to look for a stage2

It's incredibly easy to get something that will take a kernel and initrd
and even do some basic munging of isolinux.cfg -> syslinux.cfg.  But
doing anything more generic requires real knowledge of what happens once
that kernel and initrd boots.  The live images use root= bits to look
for something (and expects a certain layout), anaconda expects something
else
