Or mount points - probably more appropriate.

Agreed. I didn't even know that you _could_ change the installation
directory, but this _really_ isn't what you want to be doing. Actually, I'm
not sure why your installation scripts are failing - because it says that
dpkg chroots to the "instdir" directory before running the scripts, so I
would expect all the installation scripts to work fine. Unfortunately, it
will leave your applications in places that are unexpected by all software
other than dpkg. This would be a Very Bad Thing. The "instdir" option
would be intended to make it possible to install a system that will be run
entirely in a chroot, or even to install software onto _another_ system -
definitely not what you are trying to do.

Training? You get trained to do this? Well, I suppose the behavioral
psychologists would call learning by trial and error, "training" :-)
