The ifup@.service is triggered by a udev rule and responsible to handle
allow-hotplug interfaces.

It basically works the same as in wheezy.
The difference is, that in wheezy, the udev rule [1] called ifup
directly, under systemd it calls
ifup@<interface>.service, and this service does nothing else then run
ifup <interface>.

This has the benefit, that systemd can track it properly.

Why is it that all of the instruments seeking intelligent life in the
universe are pointed away from Earth?
