If the OS is not Linux, the code could end up generating a recursive symlink.
This can happen because the same symlink can be created twice in a row. If this
happenes, the second symlink becomes a link to itself within the directory
pointed to by the original link.
In order to prevent this, verify that the destination does not already exist.
