I'm on my ubuntu workstation right now, they seem to have incorporated that
thing already (which would work with any demon, i found at my workstation
at home that squid restarts whenever I fire up the VPN to the office):
/etc/dhcp3/dhclient-enter-hooks.d/ntpdate
/etc/dhcp3/dhclient-enter-hooks.d $ cat ntpdate
NTPDATE_CONF=/etc/default/ntpdate
NTPDATE_DHCP_CONF=/etc/default/ntpdate.dhcp
--snip--
ntp_servers_setup_remove() {
rm -f $NTPDATE_DHCP_CONF
}
ntp_servers_setup_add() {
if [ -e $NTPDATE_DHCP_CONF ] && [ "$new_ntp_servers"
= "$old_ntp_servers" ]; then
return
fi
if [ -z "$new_ntp_servers" ]; then
ntp_servers_setup_remove
return
fi
tmp=$(mktemp "$NTPDATE_DHCP_CONF.XXXXXX") || return
chmod --reference=$NTPDATE_CONF $tmp
chown --reference=$NTPDATE_CONF $tmp
(
echo "# NTP server entries received from DHCP server"
echo "NTPSERVERS='$new_ntp_servers'"
) >>$tmp
mv $tmp $NTPDATE_DHCP_CONF
}
ntp_servers_setup() {
case $reason in
BOUND|RENEW|REBIND|REBOOT)
ntp_servers_setup_add
;;
EXPIRE|FAIL)
ntp_servers_setup_remove

esac
}
ntp_servers_setup
