+</I>&gt;<i> Based on observation, the stuff timestamped 10:50:50 is the result of
+</I>&gt;<i> ejecting the disk, and the last few lines timestamped 10:50:54 are the
+</I>&gt;<i> result of reloading it, with the intervening 4 seconds consumed by
+</I>&gt;<i> reading the disk headers and such.
+</I>&gt;<i>
+</I>&gt;<i> I seem to remember here that nothing is supposed to be using HAL, so
+</I>&gt;<i> it's puzzling as to why systemd would be trying to start it in response
+</I>&gt;<i> to the load. It's equally puzzling as to why this should suddenly
+</I>&gt;<i> affect wine, when nothing's been upgraded (this worked 2 or 3 days ago).
+</I>&gt;<i>
+</I>&gt;<i> The disk is correctly mounted and identified by KDE, and is usable by
+</I>&gt;<i> k3b and command-line utilities. k3b also detects the load event, and
+</I>&gt;<i> switches its GUI prompt from &quot;insert a disk&quot; to the actual label.
+</I>&gt;<i>
+</I>&gt;<i> Is wine still hal-dependent when it ought not to be ?
+</I>
+FYI systemd is only used here because of a dbus activation request
+coming in. Possibly there are still one old udev rules or something
+similar that installs it.
+
+Personally I remove haldaemon and lib64halX from my systems and have
+done under mga1 too.
+
+I hope it will be gone completely by mga3. I think there is still some
+old perl code using it for dealing with install media in drak* as that
+was mentioned recently. Also I think draksnapshot uses it too.
