Could you please try and wait a bit longer? > But when eth0 is connected to the router before boot starts, all works fine. > > Reverting to version 0.7.49 from snapshots.debian.org solves the problem and > boot works with and without eth0 being connected to the router. With 0.7.49, allow-hotplug interfaces were handled by udev and started in the background, not blocking the boot process. This had the downside, that services which depend on $network didn't work properly. I suspect, that it's simply dhclient trying to get a lease and you simply need to wait for it to time out. If you add systemd.debug-shell to the kernel command line (man 7 kernel-command-line), you can switch to a root shell on vt9 during boot and inspect the system. The output of "ps aux", "journalctl -alb" and "systemctl list-jobs" might be helpful. As for the operstate check: I did remove this check, because even with a cable plugged in, I got "down" when running "cat /sys/class/net/eth0/operstate" in my test VM, so /etc/init.d/networking never configured the interface, so this check proved to be not really reliable. Andrew, I guess what you want to do here is have some kind of link detection? Why is that part of the init script an not ifup itself? -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
