On todays :debian: Sid upgrade I got an unexpected surprise:
Looks like ISC is ending its maintenance of isc-dhcp-client (dhclient).

"ISC DHCP Client and Relay End of Maintenance"
https://www.isc.org/blogs/dhcp-client-relay-eom/

AFAICT there are 2 alternatives for Linux:
- Busybox' udhcpc
- dhcpcd

I'm not too sure whether udhcpc is a proper replacement ...
(especially on #Debian which still has BB version 1.30 😕)

Any others?

https://xkcd.com/2347/ comes to mind 🤔

I think systemd-networkd is an option too, or does that use one of the third-party DHCP clients?
Nice one :)

I doubt it uses a third-party client ... that's not how systemd rolls ;-P and it also has their own configuration snippets which makes it even likelier that they implement their own client.
