title: Increase reliability of capistrano deploys
body: <p>I've used capistrano for a long time, but always for sites that weren't critical. If something went wrong, a few minutes of downtime weren't a big problem.</p>
  
  <p>Now I'm working on a more critical service and need to cover my edge cases. One of which is if my local connection to a server becomes interrupted in the middle of a deployment.</p>
  
  <p>One solution I can think of is to do deployments directly from the server, inside of a screen session. This seems like a reasonable and obvious solution, but I'm surprised I've never read about it elsewhere or even seen it recommended in the capistrano documentation.</p>
  
  <p>Any pointers / tips are welcome. Thanks!</p>
