The problem

Initial situation

Using Fedora 38, say you want to update the package albert from manuelschneid3r, hosted at https://software.opensuse.org/download.html?project=home:manuelschneid3r&package=albert.

And with dnf update, you get the following output:

~ sudo dnf update
Dependencies resolved.

Think twice before abandoning Xorg. Wayland breaks everything!

Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.

Wayland proponents make it seem like Wayland is "the successor" of Xorg, when in fact it is not. It is merely an incompatible alternative, and not even one that has (nor wants to have) feature parity (missing features). And unlike X11 (the X Window System), Wayland protocol designers actively avoid the concept of "windows" (making up incompr

Fedora Feature Macros

Fedora feature macros (also dubbed USE macros) provide a simple way to configure common package build-time options, affecting available features, dependencies, or subpackages provided.

Reasoning

Packages are the main building blocks of our distribution. Introducing build-time, configurable options allows for additional packaging flexibility, greater potential testing, encourages cleaner dependencies and passing explicitly defined build-time options preventing unexpected build results when upstream defaults or the build environment change. Futhermore it gives our users, as well as downstream distributions or other variants, freedom to easily rebuild our packages without modification simply by adjusting the macros they provide.

USE macros define build features in a uniform manner for the entire buildroot and can be defined either globally or per package, enabling the usage of package-specific, non-standard features or explicit overrides of the default settings. The advantage of
