That would make the order of operations for a smooth migration as
follows:
1. ifupdown switches from Recommends "isc-dhcp-client | dhcp-client" to
Depends "isc-dhcp-client | dhcp-client".
2. isc-dhcp-client drops from Priority: important to Priority: optional
3. ifupdown switches from isc-dhcp-client to dhcpcd-base.
