    Possible fix for barcode sometimes not showing up on initial boot
    
    While we can't pinpoint the reason for the barcode disappearing, the
    best guess is that sometiumes the cache dir is being created by some
    other method that might encounter a race condition with GIS so this fix
    makes sure that we have that directory before trying to write the
    barcode image to it.
