Before it attempts to start the X Font Server, the xfnts_start method calls svc_validate to verify that a proper configuration is in place to support the xfs daemon (see "The xfnts_validate Method" for details), as follows.
rc = svc_validate(scds_handle);
if (rc != 0) {
scds_syslog(LOG_ERR,
"Failed to validate configuration.");
return (rc);
}
