Comment # 18 on bug 1222314 from Stefan Hundhammer

So now we have a completely different scenario (one-click package installation
instead of system installation), and it changed the component back to YaST.

Why? We still don't write that file.

If there is a new problem in TW, and not in Leap 15.5, the conclusion is that
there must be a difference between both. What is that difference?

The one-click installation just adds a new repo, installs one package, and then
removes that newly added repo. Why would it read anything about the locales? I
don't see it adding or removing any locale.
