Isn’t it true that the moment Buster becomes stable testing will be this new distribution (Debian 11 Bullseye)?
How is antix going to handle the change?
If you are willing to stay with buster then you should change “testing” to “buster”, if your are willing to jump to bullseye then be prepared for a big upgrade after the transition.
