[Pkg-bluetooth-maintainers] Bug#643321: Acknowledgement (no bt after upgrade (4.94-2 -> 4.96-1))

[Trent W. Buck]

OK, yes, that mv_conffile fuckup is the cause of this problem.
Moving it back *and* restarting dbus and bluetooth daemons fixed it.

I didn't realize at first that hcitool talked to the daemon; its
manpage gave me the impression that it talked directly to the devices;
that the bluetooth daemon was merely some higher-level thing.

It might be useful to mention in the manpages that bluetoothd *needs*
a system dbus to do anything at all, and likewise hcitool *needs*
bluetoothd.  It might also be useful for "hcitool scan" to report
something like along the lines of "I can't see bluetoothd" rather than
"no devices found".
