| # This script creates a systemd service to turn up | |
| # the keyboard backlight at startup as it's not | |
| # respecting the last setting | |
| # In order to do this, we have to change the perms, | |
| # then echo a value into the brightness file. | |
| # The latter has to be done via a script as just | |
| # running the echo from systemd does not work. |
