> This is indeed an issue. The trick when you get new hardware is that you install Testing but you don't configure your repositories as "testing" you configure them as the name of the current testing distro: "bullseye" today. So if I keep updating my Debian Bullseye, once it gets branched I will be effectively out of testing, then Bulleye will get released and I will be on the stable repository.

Thanks for the tip.
