Readers would have to wonder if .git/packed-refs existed before, or what git command that follows this part cares about its last modified time, or what behaviour the timestamp would affect. What you are interested in doing with this is to ensure that *AN* *EMPTY* file exists there, hence you should say >.git/packed-refs && instread.
