The Vulkan LoaderAndLayerInterface [1] states that /etc/vulkan/icd.d is the "Location of ICDs installed from non-Linux-distribution-provided packages", and that /usr/share/vulkan/icd.d is the "Location of ICDs installed from Linux-distribution-provided packages". x11-drivers/nvidia-drivers installs the ICD JSON file in /etc/vulkan/icd.d, but this seems incorrect since it's a Linux-distribution-provided package, it should be in /usr/share/vulkan/icd.d. This is a low priority: the existing location does work, with no loss of functionality.
