Today I did a new TW install after more than 3 years since I did it last. Everything went smoothly as ever.
However, I see that “cdn” and “openh264” repos were installed automatically. I understand that the cdn repos are there to improve access and latency, I am not so familiar with the other one at the moment.
The question to the community is how do the “cdn” and traditional “download” repos interact. I tried removing one of the cdn repos but it was added on the following zypper ref. Should I leave the repo list as is is?
