 Ah, it might be that one. I'll try removing it. Thanks for the pointer.
 
 In any case, do you think that ntp should depend on named though? I would
 assume that most people are using hostnames for their ntp servers and not IP
 addresses, but I do see that it's possible to run ntp and not rely on
 DNS. In which case the downside of that extra dependency would be that ntp
 gets started a bit later than necessary.

Not everybody runs named, so we can't depend on it.  I think there
is also a way to say start it before us if it's available.

But ntp can perfectly start without the nameserver working.  You
might not have a network connection at the time you boot.  ntpd
will start a slave process to do the resolving in that case, and
so can resolv it later.

 The initscript for ntp should add a dependency on $named because it fails
 to start when resolv.conf is set to 127.0.0.1 and the local dns server is
 not yet running.

There are a few cases that might cause you problems.  The most
likely is a config error.  Please check that you have the
following 2 lines in your config file:
restrict 127.0.0.1
restrict ::1

You most likely have a restrict 127.0.0.1 nomodify

This is what I've got in my /etc/ntp.conf:

  $ grep restrict /etc/ntp.conf 
  # Note that restrict applies to both servers and clients, so a configuration
  restrict -4 default kod notrap nomodify nopeer noquery
  restrict -6 default kod notrap nomodify nopeer noquery
  restrict 127.0.0.1
  restrict ::1
  #restrict 192.168.123.0 mask 255.255.255.0 notrust

This is the error message I see in my logs:

  ntpdate[1547]: name server cannot be used, reason: Temporary failure in name 
resolution
  ntpd[1595]: signal_no_reset: signal 17 had flags 400

Cheers,
Francois
