+Consider also adding
+[RPMFusion through their OSTree instructions](https://rpmfusion.org/Howto/OSTree).
+The _Major releases_ uninstalling and installing is especially important so it
+switches from local package to layered package, which also affects all other
+third party repositories such as `google-chrome-stable` if it was added. While
+there is repository breakage risk stopping system upgrades, at least it will
+upgrade itself as opposed to errorring about being a local not upgraded package
+in the future.
+
+Why RPMFusion? At least `Broadcom BCM43142` wireless NIC requires
+`sudo rpm-ostree install akmod-wl kernel-devel` from `rpmfusion-nonfree` and
+there are likely other such devices/drivers as well.
