Examples could be things like specific configuration defaults or general decision-making in leadership.
What would you change?
Yes it runs quite stable. But the packages and their configuration can change.
If you’re looking for something more conservative, the stable branch fits better but on a desktop it’s very old (like an Ubuntu lts)
thats precisely my problem with debian stable, but id be ok with testing if it doesnt break unpredictably with regular updates.
On my side it’s running since years without problems. I would never use arch on a business workstation with debian testing I see no problems at all.
