..I _have_ gotten away with adding "exit 0" lines in these scripts to
make and/or keep apt and dpkg happy, I'm not saying this didn't cause
problems elsewhere.
..chk the dpkg --force-help options for better ideas.
..some commands in these install script can be made more verbose
adding the occational -v or --verbose whereever you want them.
..also play with nice and cpulimit etc to slow down apt and dpkg etc
enough to stay in control of your machine, so you can see WTF is going
on in there.

Scenarios always come in sets of three:
best case, worst case, and just in case.
