The default on my laptop is annoyingly bright, and this is a useful
feature to mitigate that. The backlight script is largely a copy of the
mixer service which provides the same value for mixers, but this one is

Note that it's off by default to avoid interference with DEs, and
document the capability in backlight(8). Set backlight_enable=YES in
rc.conf(5) to enable save/restore.
