Ok, I'll bite.  If you look under /sys/devices for "dev" nodes, how do you 
tell if you've got a char device or a block device?  (I'd really like to 
know.)

(This is glossing over the fact that searching through an arbitrarily 
large /sys tree could be very slow on certain systems, and a lot of embedded 
stuff is using 100 mhz processors and such, and prefer mdev to udev for the 
_speed_ as much as for the memory savings.)
