Comment 2 for bug 745008

There's some validity in having /var/lib/dhcp3 files still exist: we don't remove the old leases unless the user specifically removes the transitional dhcp3-client packages. That seems to be a decision that was made in Debian, and I think it makes some sense -- later, upgrades from 11.04 should probably remove these files. I'm removing the assignment for now and setting this back to Triaged because it needs to be brought up to the Debian maintainers of isc-dhcp.

Much of the same goes for samba: seems like the enter/exit scripts were created in /etc/dhcp/dhclient-*-scripts.d as symlinks to the same scripts in /etc/dhcp3; and changing this would need to be done in Debian.
