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

[Bryan Gonzalez]

Restarting the networking subsystem is not a task that a user would need
to complete on a regular basis. I grant you that. However, there are a
few times that this is necessary and it is not acceptable to respond: a)
"don't perform said task" or b) "perform it using another command X"

The problem is that we have a method to perform this task that is tried
and tested for many years. If the functionality is defunct, then it
needs to be removed so that all the content online can be updated so
that new users are not confused. OR The functionality needs to be
updated to work with the current programs.

Inaction is not an option. It's against the creed.

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
