Ever since it appeared, even when it was in Testing, I have had trouble with Buster. Oh, I could do all sorts of stuff in a VM but that doesn't count when installing on real hardware. Like many users I have my personal requirements. My preferred method for install is to start with a headless system that has basic utilities and ends at a black screen with a cursor. Then I add what I want. I've done this through at least 4 versions of Debian. I never had a problem until I met Buster head on. A couple of dozen times I have tried to install Buster on a spare hard drive and slammed into a Wifi wall. I could install MX, Antix, Devuan and a mess of non-Debian OS but not Buster. Well I can be a stubborn old git and I dug in. This machine only needs one Net connection. I do not use Network-Manager, Wicd or the like; I just write a short script in /network/interfaces. I've used the same script for a very long time without problems.
I'm absolutely stunned! Some twit has changed wlan0 to something that looks like a comic book swear word and believe me, I've used many. Does Debian employ a sadist to dream up changes like this? Aaaaauuuuggghhhhhhh!
