>1) If I reboot the device, the service does not get activated automatically. I verified this by running the method call  >org.freedesktop.DBus.ListNames (on System Bus). But If I run the executable manually, the service is registered successfully to system >bus and I can see the name listed with the method call org.freedesktop.DBus.ListNames. Why is the daemon not launched automatically?

I found that the issue #2 was because i missed a stupid / in the path while sending the dbus signal. The path should be '/org/maemo/vicar'. 

I am still not able to launch the deamon app at startup (#1). May be I got the whole Dbus service activation concept wrong. I will worry about that later.

As of now I am launching my daemon app by adding an upstart script to /etc/event.d directory. It is launching fine now.
