First taste of Debian 12
As some of you may know, the Debian project released v12, bookworm to stable on the 10th of this month. I haven’t had a reason to try it yet, but I’m downloading it now. My first thought is that it’s much larger than I expected. The normal sized version used to fit on a CD-ROM…
