Raspbianを実行しているRaspberry Piがあり、初期化するとこのエラーが表示されますifplugd。
ifplugd(lo): Program execution failed, return value is 1.
ログセクションを見ると、開始された場所で終わるように見えますifplugd initializing。おそらく、プロセスが最終的に成功したことを示します。
私のイーサネットには既知の問題がないので、このエラーがどれほど重要かわかりません。

関連性がない可能性がありますが、mtp-probeログのこの部分からアクセスされていることがわかります。最近、次の種類のログエラーが発生しました。
Nov 26 21:50:51 raspberrypi systemd-udevd[184]: failed to execute '/lib/udev/mtp-probe' 'mtp-probe /sys/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.1 1 3': No such file or directory
それから私は去ったapt-get install libmtp-runtime。
