Comment 2 for bug 796169

This doesn't work because u1sdtool connects to syncdaemon through the session DBus.

If you do have a session running on that system, I believe you can set a environment variable to point u1sdtool to the right session. If you don't, there is a way to start one and then make u1sdtool use it.

I don't have that information handy right now, but if you want it I can find it for you.
