You are lying to me and trying to lead me in the woods. The stuff you say is stuff people say that in the end don't end up being true. It does not even agree with the reality of how the system works currently. They are nonsense rebuttals and anyone with enough knowledge would be able to refute them. You're playing mind games here. Any system needing to take into account that some urgently needed networking device might shop up after 3 days when the moon is in the right position in the sky.... this is what you are saying. It doesn't agree with reality and I am not going to respond to this nonsense. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
