mkcdrec can do all this for you itself.
You configure settings
create an ISO
burn it to dvd
boot to it.
Enter rescue mode.
if you want full system recovery - bare metal....
cd /etc/recovery
./start-restore.sh
if you want single filesystem restore....
./clone-dsk.sh
And ofcourse you can still do it all manually and extract from the tar
files stored on the dvd.
its all documented.
