We also use that file as the license file. Thus, the file when it is downloaded has a specific hash, but when saved by legal-info, it has a different hash. However, we can't store two different hashes for the same _filename_ with different content. So, we extract the license file as a pre-patch hook, and store it in a separate file, for which we can now add a hash.
