Well the setupdb database includes version information (always as), so
that any change in its format may be reflected (for obvious reasons).
In practice, there have been very few changes to the XML format and most
of the time this warning can be just discarded.

Well that's a perfectly valid solution. IMHO, it is not necessarily a
good thing for all games out there to use the default ".loki" prefix. It
is easily changeable via a configure option for setupdb, so you might
as well use a different prefix if you are not affiliated with Loki :)
On the other hand, it should be noted that at least the uninstall
program tries to update itself upon each installation. There is always a
cached binary in the user's ~/.loki/installed/bin directory. I guess a
similar mechanism could be introduced for loki_update, so that
installing a newer product could trigger an automatic update of the
