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@mit list would be
the place for that discussion....
