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

[Steve Langasek]

I don't believe that this has anything to do with an "upstart/sysvinit
conflict".  The problem is simply that "restart networking" is not a
sensible thing to do on a desktop system.

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
