[LUA] WindowManager: Awesome - Checking OS and assign different icon
Heyas

I'm having a bad time to fix this.
Code is just related samples, paths are edited, take: ~/.config/awesome as 'base/config' (dot) dir.

Situation:
Recently i actualy started to have 2 different kinds of gnu/linux installed, with this, the abition raised, to get a distro specific icon displayed in the shared WM configuration because of the shared /home partition.

After some tweakings i've managed to get the WM reloaded without issues, but still, no icon is displayed, in neither of the OS'.

rc.lua
Code:
-- Functions
	-- Its just a workaround for an 'unstable' 'hwmon/hwmon[12]' definition of Fedora21 - Rawhide
	-- Function (only) from: http://stackoverflow.com/questions/4990990/lua-check-if-a-file-exists
	function file_exists(name)
		local f=io.open(name,"r")
		if f~=nil then io.close(f) return true else return false end
	end

-- Themes define colours, icons, and wallpapers
	beautiful.init(awful.util.getdir("config") .. "/themes/sea/theme.lua")

	os_icon = wibox.widget.imagebox()
	if file_exists("/etc/favicon.png")
	then	-- Its either fedora or provides same functionality
		os_icon:set_image(beautiful.icon_fedora)
		naughty.notify({ preset = naughty.config.presets.critical, title = "Its fedora", text = err })
	else	-- Probably Arch
		os_icon:set_image( beautiful.icon_arch )
		naughty.notify({ preset = naughty.config.presets.critical, title = "Its arch", text = err })
	end

-- Show the menu entry with icon
	mylauncher = awful.widget.launcher({ image = beautiful.os_icon,
		                             menu = mymainmenu })

And within the ./themes/sea/theme.lua there is:
Code:
theme.icon_fedora 	= "/etc/favicon.png"
theme.icon_arch 	= themes .. "/sea/arch_icon_16.png"

I do get a msgbox saying "Its arch", but i dont get an icon.

Any ideas or hints please?
Thank you

EDIT:
Note that 'beautiful' is the class providing the items of the active theme.

NAME

       awesome - awesome window manager

SYNOPSIS

       awesome [-v | --version] [-h | --help] [-c | --config FILE] [-k | --check]

DESCRIPTION

       awesome is a window manager for X. It manages windows in different layouts, like floating or tiled. Any layout can be applied dynamically,
       optimizing the environment for the application in use and the task currently being performed.

       In a tiled layout, windows are managed in a master and stacking area. The master area contains the windows which currently need the most
       attention, whereas the stacking area contains all other windows. In a floating layout windows can be resized and moved freely. Dialog
       windows are always managed as floating, regardless of the layout currently applied. The spiral and dwindle layouts are special cases of the
       tiled layout where the stacking area is arranged in a spiral for the former or as a rectangular fractal for the later.

       Windows are grouped by tags in awesome. Each window can be tagged with one or more tags. Selecting certain tags displays all windows with
       these tags.

       awesome can contain small wiboxes which can display anything you want: all available tags, the current layout, the title of the visible
       windows, text, etc.
