Everytime you update your kernel using Pacman, the older kernel's files are
removed. This lead some stuff to stop working, e.g. VirtualBox, Docker, USB
serials, etc.. The only thing you can do is just reboot so the new version of
the kernel will be used.
I discovered a simple hook, installable from the AUR that prevents that:
<pre><code class="lang-sh">$ yay -S kernel-modules-hook
</code></pre>
it basically backups your kernel before the update, and restores it afterward.
That's all it takes.
