Theo de Raadt has made a change in the OpenBSD-current codebase, which serves as the foundation for the upcoming significant release, removing the DHCP client dhclient. Instead of dhclient, a constantly running background process called dhcpleased is recommended, starting with OpenBSD 6.9, which utilizes the ifconfig utility for enabling the auto-configuration of network interfaces via DHCP (enabled by executing 'ifconfig $if autoconf' or adding 'inet autoconf' in /etc/hostname.$if). Starting with OpenBSD 7.0, the dhcpleased background process has been enabled by default, and the dhclient utility has been relegated to an optional status. The code for dhcpleased, along with resolvd, slaacd, and unwind, was written by Florian Obser to simplify and unify the auto-configuration of network interfaces.
