Unfortunately, no, at the moment that's the best way.  (Or use  
multiple processes.)

I'd actually thought about implementing an interface to take the extra  
input argument, because it would clean up how some of the KDC  
initialization works right now (which uses a private variant of  
krb5_init_context that only differs in that it adds the kdc.conf file  
to the normal list of config files).  Do you want to propose and  
implement something along those lines?  The krbdev at mit list would be  
the place for that discussion....
