> The get_file_size subroutine in Linux.pm is pretty tricky. The size of a file isn't as straightforward as one would think. It currently returns the `ls` size of the file which is not accurate when the actual size of a .vmdk file is requested.  The `du` size is more relevent.  The subroutine doesn't use `du` because it doesn't exist on ESXi.  Instead, `stat` is used and the sizes are calculated based on blocks used and block size.
