"It seems like operations that communicate with userspace are
really discouraged. And I am not arguing with that. Although it
doesn't mean that they cannot be accomplished. A driver loads
configuration that could be stored only on HDD. When MS Windows XP
boots up it remembers that I have turned Bluetooth off so it is not
powered on, unlike even the latest Linux (Fedora 14 at the moment
of writing) – such functionality in many drivers was not
implemented. When developer uses procfs or character devices there
should be another software or script in boot sequence that is
actually sending information from a file to particular device."
