    1) Add `--no-install-recommends` option to `apt-get install`, this
       avoids lots of (~30MB) unnecessary packages.
    2) Add `ca-certificates` package for `wget` fetching stuffs from Amazon
       S3.
    3) There is no need to run `apt-get clean` for an image derived from
       official Ubuntu since they already cleaned (see also:
       http://goo.gl/B2SQRB
    
    ) all the garbages produced by `apt-get`.
