This is brittle as during early boot ifup is prone to fail: / might still be read-only, /var might not yet exist or be writable, dhclient-enter-hooks.d/ or if-up.d/ hooks might silently fail, etc. It is also unnecessary as networking.service will bring up all "auto" and all present "allow-hotplug" interfaces anyway, and it runs at the right time. We should make either 80-ifupdown.rules or ifup@.service ignore events until networking.service is active, or wait until after it has run (slower, but avoids race conditions when hotplug events happen while networking.service is running). Thus we need to add After=networking.service to ifup@.service, so that this only does stuff after doing the "coldplug" configuration. This also affects cloud-init's setup of networking: this currently jumps through a lot of bad hoops to make sure that ifup@ does not run until after cloud-init-local.service. This includes blocking udev rules for an indefinite time, which is racy, a potential deadlock, and highly non-elegant. https://bugs.debian.org/752919 is related to this issue.
