Is there any way to group hosts so that a group can be specified in the serverclass.conf whitelist/blacklist rather than hostname regexes? Past a certain number of hosts using regexes like that gets complex and needs to be repeated for each stanza. I'd rather set up a 'webserver' group and throw all my web servers in it and then use that for the various stanzas that want to address those servers.
You may group servers by:
You can also group them by the type of operating system.
...so if you have servers named like web01 and web02, you can include them with one whitelist
You may also set the clientName to 'webserver' on each box in deploymentclient.conf, such that you could use
You can often achieve the result via inheritance - but I see your point. It is not possible to explicitly say one serverclass contains another serverclass. This would be a great enhancement request.
