[Novalug] basic Q's about flash boot of live CD

I wasn't aware you could run "yum update" on the Live USB either.
I thought you had to completely rebuild the Live USB, because
it too is an immutable Squashfs. So either you're missing my point,
or I'm more ignorant of recent changes.
Stateless is stateless. It defines what directories are immutable
and what directories are temporary/persistent. Again, I do not
believe you are correct when you say you can run "yum update"
on a Live USB boot. But I haven't tried the latest Fedora Live USB
either. But I'm fairly certain this is the design.
To change the binaries you still need to completely rebuild the image,
regardless of the media. I'll take the time to build a Live USB
myself from the latest Fedora 12 in the next few days to confirm
this is how it still works. Because unless stateless has changed
radically, and lets you overlay anything and everything without
radical reconfiguration, your statements (based on testing?
or assumption?) sound wholly incorrect from how I have known
stateless to work with the Fedora initrd-init through at least
That's why I say there is no difference between Live CD and Live
USB, except for the fact that you can write a few directories
to the Live USB - but a yum doesn't sound like its possible.

I never said it was a different image. But it's implementation is
different; one is persistent the other is not. One requires a separate
part setup for "home" the other does not. In those two areas, the
functionality of the image becomes very different. Technically we start
from the same ISO - but try to run "yum update" on your CDROM live image
and report back to me what happens. Try the same with the USB, and
you'll realize how big a difference it makes.
