RIP dhclient(8)

Friends, dhclient(8) in OpenBSD is no more, at least for those of us running -current.

For some of us it is basically in muscle memory to type doas dhclient $wifiinterface when visiting somewhere, but from this day forward we will rely on dhcpleased(8) to do its job, which in my own experience does admirably.

In this commit, Theo de Raadt (deraadt@), executed the removal.

Log message:
delete dhclient(8).  ipv4 dhcp leases have been acquired by the
always-running-in-background dhcpleased(8) for a while, which is
activated per-interface with "ifconfig $if autoconf', or
"ifconfig $if inet autoconf", or with "inet autoconf" in /etc/hostname.$if
dhclient(8) has done execve(3) of ifconfig(8) to handle this for a while,
so everyone has moved to the dhcpleased(8) method
ok florian

So long, old friend! We will remember you fondly.

And then we will look forward to this among other good things to happen in OpenBSD 7.6 in the (Northern hemisphere) fall.
