hehe, so … if you ever change the hostname of a Linux machine, you really really ought to double-check /etc/hosts to make the same hostname change there
it’s surprising just how much will break if a machine’s own hostname isn’t resolvable to a 127.x.x.x address :P
Domain search suffixes
I use DHCP for everything, even my server, with a reserved IP address in the router for the server and my desktop and a few other things I don’t want to move around (printers, some IoT things, Home Assistant, etc.).
I think the issue is the bridge interface I have to set up for Home Assistant.
