First,systemd sucks. There is no two ways about this. It violates the first rule of computer science:
Keep
It
Simple
Stupid
...(and just about any other rule of computer science you can apply to it).
Second, create or modify the /etc/rc.local to do what you want it to do. Make sure that it ends with an "exit 0" at the end. Make sure it's executable.
chmod +x /etc/rc.local
Hint: You can call other scripts from within /etc/rc.local. |
Third, create the unit file:
echo '[Unit] Description=Start local scripts (i.e. /etc/rc.local) ConditionPathExists=/etc/rc.local [Service] Type=forking ExecStart=/etc/rc.local TimeoutSec=0 StandardOutput=tty RemainAfterExit=yes SysVStartPriority=99
Next, reload systemd
systemctl daemon-reload
Start your new service
systemctl start my-rc-local
Check the status
systemctl status my-rc-local
Finally, enable it to run at boot
systemctl enable my-rc-local
