Hi,
I just want to chime in and add my support for this feature request.
Coincidently I've just done the following commit to jenkins.debian.net.git:
commit 2ccb4f0a631291f0ae3df1438b60c95d5d51374a
Author: Holger Levsen <holger@layer-acht.org>

chroot-install: work around temporarily download problems by repeating the
step once
----
I've implemented this by grepping in the output for known failure strings,
which of course is very suboptimal, so I would love proper exit codes from
apt!
cheers,
Holger
