Bug#703844: proposed wording

I'm worried that people might get confused and wrongly think that they
need this otherwise `/etc/init.d/networking stop` won't be called.
Perhaps change "before" to "right before" and add something like: "You
should only need this to handle issues with Wake-on-LAN or network
filesystems."
