Here we are back to what was proposed instead of sysctl. I have to admin
that I'm confused now about what you propose as a good solution.
Well, I wouldn't like it if we create character devices, just to let it
implement a single ioctl() ("/dev/backlight", for example). There is
only 1 parameter that's adjustable, namely the backlight intensity. A
sysctl is a good place to store such things.
I don't know.... you could flash morse code in response to a write.
In my opinion we should only use character devices for devices that
have the semantics of a file descriptor, namely to read/write data to
it, perform select(), etc. Saying sysctl is bad, because it doesn't
allow any permissions should be considered to be a defect of sysctl, not
an advantage of devfs.
The reason why I prefer consolectl, is because it already exists and
allows related graphics parameters to be configured.
