[WIP] Create helper for making init.d scripts
  this is still a WIP, just pushing it so I have a save point and a reference on my private branch before I push some stuff upstream
  this helper is intended to make adding persistent kernel toggles using non-persistent kernel fs files a breeze
  what I want this helper to do, is create a file in system/etc/init.d named 'name and then have it write command 'command'
  last I checked, I think this only has the components to make the file but not write to it
