That is not actually true. I'm using eg. a fi.tut.cs prefix and my app
works fine both in Scratchbox and on the device.

Mine does contain the full name, with the fi.tut.cs prefix, and it
works.

True, and IIRC the service file name must match this name, ie.
com.nokia.revsh.service for the above example.

This is what I do too.

How so? I don't know the internals of osso_initialize() but if your
desktop file has the correct fully qualified service name, it should be
fine, right?

Save it somewhere, you need it eg. with the rpc functions in libosso:
http://maemo.org/platform/docs/api/libosso/html/index.html. Other than
that, dunno.

I also put X-Osso-Type=application/x-executable in my desktop file,
don't know if it affects anything.

By my reasoning this file should then be called
invalid.too.revsh.service
