I checked the code on this:
gpsd/gpsd.c: openlog("gpsd", LOG_PID, LOG_USER);
So gpsd logs to "ident" "gpsd". See "man 3 syslog".
That is unique, so you can tell your system logger to route that
to wherever you want..
In syslog-ng.conf, I have:
destination gpsdf { file("/var/log/gpsd"); };
filter f_gpsd { program("gpsd"); };
log { source(src); filter(f_gpsd); destination(gpsdf); };
Viola! All gpsd messages go to /var/log/gpsd
