In /usr/share/doc/ntp/README.Debian.gz it says to remove "ntp-servers"
from the request-section to avoid generation of
/var/lib/ntp/ntp.conf.dhcp, which is automatically used by ntpd if
present.

I did so, but after an ifdown eth0 && ifup eth0 the file's still there.
When I manually remove it, it is regenerated.

/etc/network/interfaces:

  auto lo
  iface lo inet loopback

  allow-hotplug eth0
  iface eth0 inet dhcp

/etc/dhcp3/dhclient.conf:
http://paste.debian.net/50206/

/etc/dhcp3/dhclient.conf:
http://paste.debian.net/50207/

forcemerge 407336 553023
thanks

So this sounds sufficiently like #407336 that I think the two bugs can be
merged.

I'm totally unable to reproduce this problem in my test environment, but the
fact that there's two separate reports says to me that something is afoot.

Any assistance with reproducing the problem will help me get to the bottom
of it.
