Hotplugging in SuSE 10.0

Section 32.6.1 of the SuSE 10.0 Reference manual refers to the file, /etc/sysconfig/hotplug . This exists on my computer under SuSE 8.2 and under 9.3 (with enormous differences), but it is missing under 10.0 . Coldplugging consistently works under all of these installations, but hotplugging of my USB card reader only works under 8.2 . Don't I need this /etc/sysconfig/hotplug file? Where did it go?
