  $ ssh -i ~/.ssh/id_ed25519_golang1 gopher@macstadiumd.golang.org 'cp makemac makemac.old; install makemac.new makemac'
  $ ssh -i ~/.ssh/id_ed25519_golang1 gopher@macstadiumd.golang.org

On that host,
  * sudo systemctl restart makemac
  $ sudo journalctl -f -u makemac     # watch it

Updating makemac.service
