I am using systemd to handle some tasks and I have a service file which works fine once enabled with systemctl.Now, I would like to enable it automatically from the first boot.I know that putting a replacement file into /etc/systemd/system/ replaces the behavior of the file with the same name into /lib/systemd/system/.There is a way to enable a service file automatically just to putting it in some directory ?
