The Live-CD project? Packages are in the Debian repositories:-
http://mklivecd.sourceforge.net/
http://live.debian.net/
I haven't used it in recent years, but I suspect with some tinkering
it could do what you want - rescue cd, with a backup of your
customisations, configurations, and home, an archive of main packages
(space providing), and a copy of "dpkg --get-selections > selection"
which could be scripted to rebuild and/or clone a box.
"aptoncd"
AFAIK not in the Debian repositories - but you could try mkCDrec:-
http://mkcdrec.sourceforge.net/
...and it's "successor" - http://relax-and-recover.org/
There is also Debian-based Live CD, it's name escapes me, which is
kind-of Norton Ghost and it includes the ability to clone to DVD.
A simple clone (dd) would limit you to reinstalls on disks the same
size or larger - whereas cp (with the appropriate switches) will, in
most cases, work fine - if you first partition and format the new
disk. You'd need to change the UUIDs in GRUB. I've used that method
and "dpkg --set-selections < selections" and customised /etc/skel to
do what you describe but only from disks not optical media. A little
bash scripting and bashburn or similar should make it possible to put
that onto optical media. Start the restore/clone process with a tiny
rescue cd booted toram?
Generally the process you describe is done with something like
puppet/chef etc, or preseeding PXE installs, on a larger scale (SOE
deployment).
