Hi all,

I've spent the past couple of days attempting to add rudimentary support
to 'guix deploy' for some more complicated use-cases. I think I've made
some decent progress, but I've reached a point where I'm having an issue
that's beyond my abilities.

'deploy-digital-ocean' gets to a point where there's a droplet running a
"bootstrap" configuration of the Guix System, but I can't keep an open
SSH channel for sending over the operating-system configuration
specified for the deployment.
