In openrc my configuration was much simpler. I only wrote
/etc/wpa_supplicant/wpa_supplicant.conf and added to openrc wpa_supplicand
and dhcpcd services. So this worked without any actions from my side.
Systemd has lot of specific functions, adding services more difficult.
I tried 'Type=Simple' as somebody offered foo service in web and it did not
work.
I tried also 'ExecStop=command1 && command2' and it caused the error when I
stop the service.
Also I used this one I have seen in web 'WantedBy=multi-user.target' .
