How to specify group for agent on install / via CLI

[brendandebeasi]

As a user I would like to know how to tag the machine into a group on install. By poking around, I see there is a URL parameter to join/create groups, but it is not entirely clear how to make use of this.

Usage of ./sysward:
  -custom-hostname string
    	set the custom hostname for this machine
  -group string
    	join this group automatically or create it
  -hostname string
    	set the hostname for this machine
  -install
    	used when initially installing agent, disables random backoff
  -unregister
    	unregister the agent at the dashboard
  -version
    	display current version
