There were a series of issues discussed with the original authors
- lack of modularity
- incorrect interfacing to tty layer for serial units
- some security problems (not publically disclosed)
- problems with /proc config interface
- future - when you need userspace to set up serial ports or direct usb
  what will happen - there needs to be an interface lower than Linux to
  solve these problems.

  felt it was the wrong model
