[time-nuts] thunderbolt for ntpd or gpsd

I am looking for advice.

I have one of the group buy thunderbolts (thanks for all the work on 
this) and would like to use it as a local network time source.

Are there timekeeping preferences between using the thunderbolt as a ref 
clock for ntpd or connecting it to gpsd and using the gpsd to ntpd 
capability? Running gpsd is one more process to manage but does give 
access to the gps infomation on the network.

In either case, what is the preferred method of feeding the 1PPS signal 
to the server? The Thunderbolt manual does not show 1PPS on the serial 
port. I have not yet opened the case to look. Do people commonly make 
this connection inside the case or is it better to make a cable with 
serial on one end and serial and a BNC on the other end?

Thanks for any best practices information anyone can offer.
