IMHO it HAS to be backward compatible. E.g. gpsd uses the existing SHM interface, and while the maintainers are probably very willing to change the interface when an improved option is available, it is not practical to lock-step the upgrade of ntpd beyond a certain version with the upgrade of gpsd. So ntpd has to support the existing SHM interface for a while, and there has to be a mechanism to detect if a newer interface is available. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
