I just grabbed the Quantal Desktop daily image of 19-Jun-2012 and
extracted the squashfs.
There I found that resolvconf's database contains an
"original.resolvconf" record with "nameserver 10.122.37.1" in it.
Explanation: When resolvconf is installed it puts a copy of the original
resolv.conf file in /etc/resolv.conf.d/original and another copy in
/run/resolvconf/interface/original.resolvconf so that no nameserver
information is lost. The latter file (correctly) disappears at the next
reboot. I wonder if that file belongs in the live image.

============== END LOG ==============
Can someone please explain exactly how nameserver and other networking
information is passed from one program to another when booting a live
image, installing Ubuntu on a machine, (apparently) chrooting to the
installed system to run late_command, and rebooting?
A good overview of how live CDs are built would also be helpful to me.
