  --- BEGIN ISSUE ---
  NetworkManager hook notifications broken on Tails 2.x
  The invocation of `notify-send` in `securedrop_init.py` does not show a notification in Tails 2.x like it did in Tails 1.x. This is due to dbus-related changes in Debian Jessie, and is a known issue as a quick [search](https://labs.riseup.net/code/projects/tails/search?utf8=%E2%9C%93&changesets=1&q=notify-send) of the Tails issue tracker demonstrates.
  
  Furthermore, it looks like Tails has a special wrapper script, `tails-notify-user`, specifically meant for the use case of displaying notifications to the user from background scripts running as different users, so we should just use that instead.
