I thought that permanent postinstall scripts run even when no packages
are being installed, or only packages are being removed, so they they
are effectively run every time setup is?

Tempting, but I don't believe that is a good solution, since it adds the
time it takes to rebuild the info directory to every setup run.

I also don't think it sets a good example. Any other packages which
require update scripts to run (which may take even longer) when packages
are installed/removed, should not be doing that every time setup is run,
if avoidable.
