The service has Type=oneshot, which means that the default value of SuccessExitStatus=0. When multiple vtcon devices are detected, udev will restart the service after each one. If this happens quickly enough, the old instance will get SIGTERM while it is still running: [ 5.357341] (udev-worker)[593]: vtcon1: /usr/lib/udev/rules.d/90-vconsole.rules:12 RUN '/usr/bin/systemctl --no-block restart systemd-vconsole-setup.service [ 5.357439] (udev-worker)[593]: vtcon1: Running command "/usr/bin/systemctl --no-block restart systemd-vconsole-setup.service" [ 5.357485] (udev-worker)[593]: vtcon1: Starting '/usr/bin/systemctl --no-block restart systemd-vconsole-setup.service' [ 5.357537] (udev-worker)[609]: vtcon0: /usr/lib/udev/rules.d/90-vconsole.rules:12 RUN '/usr/bin/systemctl --no-block restart systemd-vconsole-setup.service [ 5.357587] (udev-worker)[609]: vtcon0: Running command "/usr/bin/systemctl --no-block restart systemd-vconsole-setup.service" [ 5.357634] (udev-worker)[609]: vtcon0: Starting '/usr/bin/systemctl --no-block restart systemd-vconsole-setup.service' ...

Let's treat SIGTERM as success so we don't get this spurious "failure".
