Network is sometimes not unblocked post-Greeter in Jessie
_Originally created by @intrigeri on [#9012 (Redmine)](https://public-redmine-archive.tails.boum.org/code/issues/9012)_
On an ISO built today from feature/jessie at
a48119d41f0083b22210b59c62ebace02ab9c7f0, after logging in the
only network adapter I can see in `ip a` is `lo`. If I manually run
`/usr/local/sbin/tails-unblock-network` in a root terminal in the GNOME
session, then the network comes up.
I cannot reproduce this with an ISO from a week ago, built from
6e49989443c85c3cfb69fefac6b4534f601f2e96. The Git diff doesn’t
ring a bell, so likely the culprit is one of:
- systemd/udev upgrade from 215-11 to 215-12
- Linux upgrade from 3.16.7-ckt4-3 to 3.16.7-ckt7-1
Feature Branch: bugfix/9012-unblock-network
