The current Ubuntu live CD squashfs doesn't get loaded into memory at
the moment, it gets mounted and then files are read transparently from
As for the RHGB/Firstboot idea, I tend to agree with you. We already do
it in tuXlabs, where we have a dialog that pops up before the desktop
loads on the live CD, asking whether the user wants to install, or use
the LiveCD. This makes it possible to install using Ubiquity on a
machine with only 128MB RAM.
