For instance, I am using a dumb DCF-77 receiver which is physically attached to /dev/cuaa1. Unfortunately the appropriate device names are hardcoded into ntpd; in my case it is /dev/refclock-0. Hence I need a symlink from refclock-0 to cuaa1 which is achieved most conveniently through a line in /etc/devfs.conf: # ntpd link cuaa1 refclock-0 Hence rc.d/devfs must be run before rc.d/ntpd. Otherwise there is a race between rc.d/devfs and rc.d/ntpd which may cause ntpd to coredump. The trivial patch below achieves this. This also applies to 6-STABLE and CURRENT. >How-To-Repeat: >Fix: --- etc/rc.d/ntpd~ Sun Oct 10 15:40:13 2004 +++ etc/rc.d/ntpd Fri Jan 13 10:13:00 2006 @@ -5,7 +5,7 @@ # # PROVIDE: ntpd -# REQUIRE: DAEMON +# REQUIRE: DAEMON devfs # BEFORE: LOGIN # KEYWORD: nojail >Release-Note: >Audit-Trail: >Unformatted:
