Binary package hint: ntp

The NTP package comes with /etc/dhcp3/dhclient-enter-hooks.d scripts to
enable the local system to discover its NTP servers via DHCP, which is a
very common configuration in an Enterprise setting.  This is good!

However, the default /etc/dhcp3/dhclient.conf file does NOT request the
NTP servers from the DHCP server; the request entry says:

request subnet-mask, broadcast-address, time-offset, routers,
        domain-name, domain-name-servers, host-name,
        netbios-name-servers, netbios-scope;

Note that the "ntp-servers" option is not present here.

The NTP package needs to have code to update the dhclient.conf file to
request those servers be delivered, otherwise the DHCP entry hook
scripts in /etc/dhcp3/dhclient-enter-hooks.d are useless.

I suppose an alternative would be to change the default "request" entry
in the dhclient package itself, to add the ntp-servers option?
