hi all

I met a problem . Does anybody help me ?
I wrote a udeve rules for ntfs filesystem mount , and i want to using
dbus-send to send a dbus signal .But it seems it can not work . When I
debuge, i saw /var/log/message said it send ok. But , in fact , it can
not work. Does anybody know this issue?

PS: When exec udev rules, it should be root , and i am using a normal
user to debug and see result.
