* lib/fpm/package/dir.rb: File.directory? returns true if source is a link to a directory. This is not the desired behavior, a link should be kept as a link, whether it is a link for a file or a directory. * templates/rpm.erb: check whether we are copying a link, if so, only copy the link not a new file. For the same reason as lib/fpm/package/dir.rb, links to directories were rejected. So, do not reject links to directories.
