The existing config sections were anonymous, implying multiple can coexist. Those are now named so that only one shall exist. Added: - smoothtime (in case of large frequency offsets) - systemclock parameters - logchange (increase awareness of clock drift in syslog) - maxsources (for peers; internal default: 4) - prefer (one server over others) - interleave (xleave - more accurate transmit timestamps - good to have) Refactored handle_allow() to handle 'list interface' instead of option. Then only a single section is required. Signed-off-by: Paul Donald <newtwen+github@gmail.com>
