> "Today, we configure clustered JBossAS instances with a "jboss.partition.name" which represents the identity of the cluster of which it is a part.  However as far as I've been able to figure out, we do not have a hard-and-fast concept of a node name.  I would like to propose a system property "jboss.node.name" which represents the identity of the node itself.  This property would have a sensible default but would also be modifiable just as partition name is today.
>  In terms of implementation, my few minutes of research on the topic indicate that the best way to calculate a default node name at boot would be as follows.
>    1. Define a system property, "jboss.qualified.host.name", which, if unspecified, defaults to the value of:
>          1. the value of the "jboss.host.name" system property, or if that is not specified,
>          1. the HOSTNAME env var, or if that is not specified,
>          2. the COMPUTERNAME env var, or if that is not specified,
>          3. the value of InetAddress.getLocalHost().getHostName(), or if that does not turn up anything,
>          4. a default value such as "unknown-host.unknown-domain"
>    2. Define a system property, "jboss.host.name" which, if unspecified, defaults to host portion of the above property
>    3. Define a system property, "jboss.node.name" which, if unspecified, defaults to the value of the above property
> Also, add the following command-line options: 
>     -H, --hostname=<name>         Set the host name
>     -N, --nodename=<name>         Set the node name to use
> (Edited with final system property names, and command line options)
