I didn't know about this script, but I will surely try it. It should be promoted
more :-)

That's why I want this integrated into mainstream, to reuse as much as
possible from the Fedora infrastructure, instead of rolling my own. Is
there a todo/bug list regarding this? I've already looked at the
livecd-tools bug list and I haven't seen anything regarding this.

It's relatively new

There's been discussion about it here a few times.  The short summary is
that mkinitrd supports all of the various methods of booting _except_
for the livecd.  But the livecd benefit strongly benefits from using
bash rather than nash as the script interpreter.  So part of the idea is
moving to where we have bash as the interpreter and nash as some of the
utilities.  But this isn't the best place for the discussion as pjones
isn't on this list
