Sure, pedantically you are no doubt correct even though I have no idea
what a 'bare metal install' means in this context.

no, I'm not talking anything that new, just standard f8 and onward.

Also here I don't really know what you mean. Though yes, LiveCD
installations are presently still less flexible in several ways than the
traditional installer. I was just pointing out that they are also more
flexible in several ways, and my rebootless installer takes both sides
of that even further.
I didn't mean to suggest abandoning the traditional installer. I mean I
am crazy, but not _that_ crazy :) I do believe however that when most
people compare a traditional DVD install, or even the fanangled
traditional DVD image on usb boot media, to the LiveCD/DVD/USB method,
with or without my novelty rebootless alternative, they will find the
experience to be drastically speedier (at least in many cases). Simply
because writing 10K files to a filesystem takes a lot longer than dd'ing
a filesystem image. (and invoking rpm to install all of them, and other
But I'm sure there are many use cases outside my knowledge which you are
presumably referring to which are speedier still, and the right choice
for some situations but not others.
What I see however, is a LiveUSB that boots purty darn fast, and allows
installation purty darn fast. In fact, I envision a LiveUSB image that
acts pretty much like most LiveUSB's you are familiar with, but which
may also have a bootloader option to take you straight into the
afore-described minimal ssh/yumable state in just a couple minutes,
without even requiring any subsequent reboot before attaining fully
operational production state.
But what I'm describing are things I'd like to experiment with building,
and present as experimental options and ideas to this list in the
future. Absolutely off-topic as far as the obvious priority #1 of this
list at the moment. So... never mind for now.
