I remember at least one setup with 4 identical servers, where each
server had a local GPS refclock configured (which for sure didn't send
the leap warning anymore after the real leap second had passed) and in
addition had simple "server" entries for the other 3 servers.
Unfortunately this was mostly handled on the phone, so I don't have any
records with details.
Anyway, I'll see if we can install a similar setup here to see if we can
duplicate this behaviour.
