File: entries in the WHENCE file overwrite existing files in the target directory, however, Link: entries are skipped if the file exists in the target directory. This can cause issues if the Link: entry is updated, but the target directory contains an old symlink. Do not skip writing Link: entries if the file exists, always create the symlink. This matches the behavior of File: entries and ensures symlinks will contain values from the WHENCE file.
