I know this problem from other packages there are several extensions, and you 
need only one at a time (e.g. hibiscus and the password-media-backends 
chipcard, pintan or RDH, and a lot of other packages which uses databases and 
support several different databases)

Yes, but If I hardcode a requirement for CDnavigator-hsqldb ... all mysql or 
postgres users will complain "... why must I install hsqldb if I want to use 
mysql...". And if I include all backends in one package, you need to install 
postgres-*, mysql-* and hsqldb packages.. And you will use only one database 
server at a time. So this is a "missing" feature in smart to express the 
correct behaviour: "Hey, you have the choice to install one of those 
packages!" and give you a short list of the possibilities.

In your case you should do a "smart install CDnavigator CD-navigator-hsqldb" 
and you're fine.

have fun with CDnavigator. Btw: it oftne happens that it crashes on the first 
start. But I couldn't figure out why, simply restart it and it works. 
Magic :)
