I created a short script to set an interface to down,
[Unit]
Description=Down
[Service]
Type=simple
ExecStart=/usr/bin/base -c 'ifconfig eth0 down'
I have done systemctl enable, and systemctl start works as expected to set the interface to down. However, on rebooting it is not executed after logging in. Is there anything I missed?
The above is done on a RPi4 with the 64-bit version of Raspberian OS.
