Solved: Capistro deploy fails with 'Permission denied (publickey).' but you know you have your permissions setup correctly

I spent a couple hours scratching me head one day when I couldn't deploy to the production server, but I could a little while ago.

The Capistrano deployment recipe had been changed to forward the ssh agent (which means that my local ssh key is the one that will be used by the deployment server to checkout the updated code from Git):

  ssh_options[:forward_agent] = true
Capistrano was complaining:
    servers: [""]
    [] executing command
 ** [ :: out] Permission denied (publickey).
 ** [ :: out] fatal: The remote end hung up unexpectedly
The solution was just to add my SSH key to my local SSH agent:
$ ssh-add
Simple enough. Turns out you have to do that every time you restart your machine tho, which is a bit annoying. Any way to avoid that?

Cheers, Karl
