Bug description:
dhclient has been used as the dhcp client in Ubuntu and debian for
many years. Over time, many packages have integrated with dhclient.
The list below is of packages that have declared a dependency and
those that have shipped hooks to be invoked by dhclient.
As we move to systemd-networkd these will have to be addressed.
# ./get-rdeps isc-dhcp-client | sort -u
breaks - initramfs-tools (initramfs-tools)
depends - dracut (dracut-network)
depends - isc-dhcp (isc-dhcp-client-ddns)
depends - libguestfs (libguestfs0)
depends - maas (python3-maas-provisioningserver)
depends - netscript-2.4 (netscript-2.4)
depends - network-manager (network-manager)
depends - ubuntu-meta (ubuntu-minimal)
depends - walinuxagent (walinuxagent)
depends - whereami (whereami)
depends - wicd (wicd-daemon)
depends - wifi-radar (wifi-radar)
enhances - resolvconf (resolvconf)

Another possible integration point that is not likely listed in the package
dependencies is reading of the leases file for additional information.
As an example, Azure advertises the location of its http based metadata
service as an option in a dhclient response. cloud-init will read the
lease files to find the correct address.
