Could these not also have gone into the relevant scripts for SysV or
init.d startups?
Which ones?
Init.d:

Create a script:

```
#!/bin/bash
# chkconfig: 2345 
# description: Set the battery charge threshold

start() {
    echo 50 > /sys/class/power_supply/BAT0/charge_control_end_threshold
}

case "$1" in 
    start)
       start
       ;;
    stop)
    restart)
       ;;
    *)
       echo "Usage: $0 {start|stop|restart}"
esac

exit 0
```

And then add it to the system using `chkconfig`

SysV - it could be as brutal as adding `echo 50 > /sys/class/power_supply/BAT0/charge_control_end_threshold &` as an extra line into /etc/rc.local

I'm just trying to gauge how systemd makes this an easy customization of the system compared to what came before it.

I'll concede that the script for systemd is a lot more readable - so perhaps that in its entirety is a win?

Cheers!
