WRT to the ppds.dat file, if you ever had a pre-1.2 version of CUPS
installed, the ppds.dat format *did* change.  It might be worthwhile
to delete this file when a package is deleted or upgraded in case
cups-driverd doesn't detect the format change...

Anyways, deleting the cache file will force a full re-scan of the
PPDs...

As for the comments about caching the PPD list in the web interface,
that is simply not possible using standard HTML forms.  Given that
we have a had requirement to support text browsers that don't
support script languages, we can't use "AJAX" or any other client-
side tricks.
