mdev and udev are exactly the same ... the kernel notifies userspace of an 
event (device is created) and they parse /sysfs for metadata about the device 
so that it can create the proper device node

the reason mdev exists is merely because udev is much larger than many people 
need/want

it isnt being deprecated, some entries in sysfs were deprecated ... entries 
that mdev relied upon
