Hey Dave,

Thanks for the initial feedback. I squashed that first commit of yours
and used the opportunity to move the addition of 'deploy.scm' into the
"Add 'guix deploy' commit". Here's the cleaned up patch set.

Jakob L. Kreuze (5):
  ssh: Add 'identity' keyword to 'open-ssh-session'.
  gnu: Add machine type for deployment specifications.
  Add 'guix deploy'.
  Export the (gnu machine) interface.
  doc: Add section for 'guix deploy'.
