    There is a long-lasting bug in the networking init file
(/etc/init.d/networking), introduced by Debian for Systemd
compatibility. It shows up and delays init when you have an ethernet
interface which isn't connected. I suggest you apply the attached patch
to this file. In addition, you should probably modify your interfaces
file so as to contain both 'auto eth0' and 'allow-hotplug eth0' - don't
ask me why, I don't know, but it works.
