Possible gotcha

This method returns a Pathname object which handles paths starting with a / as absolute (starting from the root of the filesystem). Compare:

>> Rails.root
=> #<Pathname:/some/path/to/project>
>> Rails.root + "file"
=> #<Pathname:/some/path/to/project/file>
>> Rails.root + "/file"
=> #<Pathname:/file>
>> Rails.root.join "file"
=> #<Pathname:/some/path/to/project/file>
>> Rails.root.join "/file"
=> #<Pathname:/file>
