description = ''
Mode to use to install the experimental GPU driver into the system.
driver: install only as a driver, do not replace system Mesa.
Causes issues with certain programs like Plasma Wayland.
replace (default): use replaceRuntimeDependencies to replace system Mesa with Asahi Mesa.
Does not work in pure evaluation context (i.e. in flakes by default).
overlay: overlay system Mesa with Asahi Mesa
Requires rebuilding the world.
