Because as I explained this earlier (http://talk.maemo.org/showpost.php?p=800593) , as far as I, and the Filesystem Hierarchy Standard, know /var/opt/ *is* the right place for placing variable data for packages in /opt/ hierarchy.

I was pointed out the osso_backup registeration which I have implemented already and will come out in the next update. But guess what, I still lost my progress when updating to PR1.3 using Ovi Suite. Apparently it doesn't know anything about osso backup...

I'd love to make the situation better some how but I don't know any proper solutions for this. I even lost all device settings when updating through Ovi Suite even though it stated that it will backup them.
