Update

Update an existing service unit file on a target host with a new Object Store reference. The unit file is redeployed and systemctl daemon-reload is run. Fails if the unit file does not exist -- use create first:

$ osapi client node service update --target web-01 \
    --name myapp.service --object myapp-unit-v2

  Job ID: 550e8400-e29b-41d4-a716-446655440000

  NAME             CHANGED
  myapp.service    true

If the content has not changed (same SHA), changed: false is returned:

$ osapi client node service update --target web-01 \
    --name myapp.service --object myapp-unit-v2

  Job ID: 550e8400-e29b-41d4-a716-446655440000

  NAME             CHANGED
  myapp.service    false

Broadcast to all hosts at once:

$ osapi client node service update --target _all \
    --name myapp.service --object myapp-unit-v2

  Job ID: 550e8400-e29b-41d4-a716-446655440000

  HOSTNAME  NAME             CHANGED
  web-01    myapp.service    true
  web-02    myapp.service    true

JSON Output
