Hi,
used this approach also with isc-dhcp* works like a charm:

       iface eth0 inet manual
       pre-up /sbin/ip link set $IFACE up
        up /sbin/dhclient -nw -4 -v -i -pf /run/dhclient.$IFACE.pid -lf /var/lib/dhcp/dhclient.$IFACE.leases -I -df /var/lib/dhclient6.$IFACE.leases $IFACE
        pre-down /sbin/dhclient -r -4 -v -i -pf /run/dhclient.$IFACE.pid -lf /var/lib/dhcp/dhclient.$IFACE.leases -I -df /var/lib/dhclient6.$IFACE.leases $IFACE
        down /sbin/ip link set $IFACE down

Ciao,
Tito
