Yes and no:
The ability of ntpd to disregard circular definitions, i.e. using itself
as server, made it possible for me to use the exact same ntp.conf file
for all of my 6 primary servers:
I.e. all six are listed as servers, along with a locally attached Oncore
UT+, so each server ends up with the 5 others as peers.
(Since I only have three active Oncores, one on each site, I end up with
three S1 and three S2 servers. If an S1 server should suffer a hw crash,
I can simply move the RS232 cable to the local S2 server.)
