hello,
I'm one of the linux sorcerer maintainer and I'm trying to switch 
sorcerer to udev (from devfs)
the "spells" (compile/install scripts) are done and everything install fine
hotplug scripts seems to work correctly at least for usb (some strange 
error on pci only with 2.6 kernels, some modules aren't loaded but I 
haven't investigateted further) : my usb mouse/adaptaters modules are 
loaded at boot time....
so this means : 1) pci hosts are detected 2) usb OHCI generate the event 
(detection of usbmouse) and hotplug loads the corrects modules :)
BUT :( udev don't work
running the test scripts work correctly (it's awfully long but at least 
this create some entries) after i mounted sysfs into /sys (previous 
mount point was /sysfs but udev don't work with it)
so I don't understand.....
I readed into the docs and found that udev/hotplug is now 
udev/namedev/hotplug/libsysfs but I can't find namedev stuff can it 
comes from that?
the link of udev into hotplug.d is correct and have the rights modes
if someone can help.....
