notes:
- In order to register a system, rhnreg_ks requires either a username and password, or an activationkey.
requirements:
- rhnreg_ks
options:
state:
description:
- whether to register (C(present)), or unregister (C(absent)) a system
required: false
choices: [ "present", "absent" ]

username:
description:
- Red Hat Network username
required: False
default: null
password:
description:
- Red Hat Network password
required: False
default: null
server_url:
description:
- Specify an alternative Red Hat Network server URL
required: False
default: Current value of I(serverURL) from C(/etc/sysconfig/rhn/up2date) is the default
activationkey:
description:

required: False
default: null
channels:
description:
- Optionally specify a list of comma-separated channels to subscribe to upon successful registration.
required: false
