I didn't find anything in my search for how to make BlueQuartz allow  
creation of wildcard DNS records in the DNS management UI.  So I  
plunged in to fix it myself in the BQ source.  I finally found it, and  
it appears to work great.  If anybody is wondering what I did, here's  
the run down.

Initial validation done by javascript, I added a simple * only check  
to the domainname change handler, only applies to a_host_name field.   
I'm not sure if this is best method, so any feedback welcome.  (this  
file is part of the ui/palette package in source)

/usr/sausalito/ui/web/libJs/uifc/DomainName.js:
function DomainName_changeHandler(element) {
	if(element.name == 'a_host_name') {
		if(element.value.length == 1 && element.value.charAt(0) == '*') { //  
wildcard OK, relies on dns.schema change in dns mod
			return true;
		}
	}
   if(!DomainName_isDomainNameValid(element.value)) {
     top.code.error_invalidElement(element,  
top.code.string_substitute(element.invalidMessage,  
"[[VAR.invalidValue]]", element.value));
     return false;
   }

   return true;
}

And the other change is the db.schema of the base-dns.mod  module, in  
source, not sure this can be done live.  I changed it and built the  
RPM, upgrading the base-dns rpms to mine after.  I edited base-dns.mod/ 
glue/schemas/dns.schema adding a typedef at top:

<typedef name="hostname_rsc" type="re" data="^[A-Za-z0-9\*][A-Za- 
z0-9\-]*(\\.[A-Za-z0-9][A-Za-z0-9\-]*)*$"/>

and changing the hostname field to use hostname_rsc type instead of  
hostname (I didn't want to change the base type within cce server)

~line 413:
   <property name="hostname" type="hostname_rsc" default=""  
optional="true"
     writeacl="ruleCapable(dnsAdmin)"/>

Any thoughts or comments/questions let me know.  It was always  
annoying me that we had to go edit the zone file itself instead of  
being able to enter '*' into the UI.  So now we can!
