Автозапуск программ на определенных тегах экрана

Моя цель - автоматически запускать несколько программ с определенными тегами при первом запуске awesome, например. запуск Chromium на экране 1, тег 1; запуск gVim на экране 2, тег 1. Я нашел несколько мест в Интернете, которые рекомендуют использовать следующую функцию:

function spawn_once(command, class, tag) 
  -- create move callback
  local callback 
  callback = function(c) 
    if c.class == class then 
      awful.client.movetotag(tag, c) 
      client.remove_signal("manage", callback) 
    end 
  end 
  client.add_signal("manage", callback) 
  -- now check if not already running!     
  local findme = command
  local firstspace = findme:find(" ")
  if firstspace then
    findme = findme:sub(0, firstspace-1)
  end
  -- finally run it
  awful.util.spawn_with_shell("pgrep -u $USER -x " .. findme .. " > /dev/null || (" .. command .. ")")
end

spawn_once("chromium", "Chromium", root.tags()[2][1])
spawn_once("gvim", "gVim", root.tags()[1][2])

К сожалению, эта функция не работает в новых версиях awesome. Независимо от того, какой тег я выберу или внесу незначительное обновление в функцию, он помещает программу в первый тег. См. комментарии: https://gist.github.com/Flowkap/8858434

Не работает должным образом. То же, что dvd001. Таким образом, программы запускаются с тегом 1 независимо от указанного тега.

Как мне сделать это в более новых версиях awesome (v4.2+)?

Вот мой rc.lua:

end
