You might want to make it a character device driver. And write a small
userland control program. Sysctl isn't really made for this kind of
functionality.
No. sysctl is good for doing stuff like this. An even better approach
So you want that either
- a daemon running as root is written which listens to user
requests to set the backlight via sysctl
or
- a SUID root program is written that sets the backlight
via sysctl
instead of
- a character device with appropriate filesystem permissions
which allows to not go the SUID root or daemon running as
root way
?
