[Bug 1072518] Re: Restart networking crashes dbus and the desktop manager

[Launchpad Bug Tracker]

This bug was fixed in the package ifupdown - 0.7.47.2ubuntu2

---------------
ifupdown (0.7.47.2ubuntu2) trusty; urgency=medium

  [ Stéphane Graber ]
  * Allow setting the MTU and HWADDR on manual interfaces. (LP: #1294807)
  * The above change also means that manual interfaces will now be
    brought up and down (ias many users expected until now).
  * Disable link.defn as it's not covering all the cases supported by
    the vlan and bridge hooks and so causes more harm than good at this
    point. (LP: #1295304)
  * Also enable network-interface-container for OpenVZ. (LP: #1294155)
  * Update networking.init to exit 1 on reload when on an upstart system.
  * Pass --force to ifdown in network-interface to silence errors on
    non-existing interfaces. (LP: #1295620)

  [ Dimitri John Ledkov ]
  * Prevent the ability to stop or restart networking service
    interactively. As that is not supported. Networking job is only stopped
    during shutdown sequence. (LP: #1072518)

Bug description:
  =========== WARNING ===============

  Doing:

  sudo restart networking

  or

  sudo /etc/init.d/networking restart.

  ============ WILL TEAR DOWN MOST OF YOUR DESKTOP =============

  Networking is a generic job which brings up all networking interfaces
  in the right order at boot.

  It should never be stopped nor restarted.

  It is only stop at shutdown to correctly bring down all the networking
  interfaces in the right order again.

  =========== DO NOT RESTART NETWORKING ===============

  If you want to reconfigure all networking interface you can use
  something like:

   ifdown eth0
   ifup eth0

  Or all interfaces with:

   ifdown -a --exclude=lo && ifup -a --exclude=lo
