I'm planning to have mirrormagic use debconf to ask the user if they want to
delete the highscore files from the older version (which are incompatible
from the new).
Having a choice of Yes/No is clear, but it seemed to me it might be
appropriate to provide a third alternative, "Quit", which aborts the upgrade
of mirrormagic.
What is the usual approach to handling the aborting of a package
installation? Is it appropriate to "exit 1" in preinst if the user chooses
"Quit", halting the installation of the package?
Or is this simply a Bad Idea, and the user should be expected to use Ctrl-C
if he really wants to quit the installation?
