Bug#527331: Error handling is dodgy
Live-helper doesn't propagate errors correctly. If something goes wrong
during the installation, live-helper will not propagate the return code,
which means that you need to carefully scan your logs in order to find
out if everything is okay.
Here's an example:
Unpacking xserver-xorg (from .../xserver-xorg_1%3a7.3+18_i386.deb) ...
xargs: apt-get: terminated by signal 15
P: Begin unmounting filesystems...
The ``Done!'' is printed by my script, and indicates that lh_build
returned status 0.
