title: why is the cabal sandbox inited after installing yesod-bin?
body: <p>On the Yesod homepage (<a href="http://www.yesodweb.com/page/quickstart" rel="nofollow">http://www.yesodweb.com/page/quickstart</a>) the following installation sequence is suggested:</p>
  
  <pre><code>wget http://www.stackage.org/lts/cabal.config
  cabal update                       # download package list
  cabal install alex happy yesod-bin # install build tools
  yesod init --bare                  # answer questions as prompted
  cabal sandbox init                 # set up a sandbox
  cabal install --run-tests          # install libraries
  yesod devel                        # launch devel server
  </code></pre>
  
  <p>My question is:
  why is "cabal sandbox init" not directly after "cabal update"?</p>
  
  <p>In the suggested way alex happy yesod-bin are all installed in the global space instead of inside the sandbox.</p>
  
  <p>Thanks,
  Alex.</p>
