Newer kernels (since torvalds/linux@abb139e75c) try to
read firmware directly from the filesystem before falling back to a
userspace helper (udev) if firmware cannot be found (in even newer
kernels, the fallback path can be disabled altogether). By default, only
certain paths in /lib/firmware* are searched, so this was initially not
helpful for NixOS.
Since torvalds/linux@2760284206 (which,
based on the commit message, was implemented just for NixOS, go us!),
though, an extra path can be dynamically prepended to the search path.
So do that, in three ways:
1. Pass a kernel command line option in case the module is built-in
2. Add a line to modprobe.conf in case the module isn't yet loaded by
activation-time
3. Add an activation script to set the option in /sys in case the module
is already loaded by activation-time.
The upower daemon needs the gdbus command (which is weird given that
upower links against dbus_glib, but ah well...). This fixes suspend
in KDE with systemd.
The VirtualBox build in Nixpkgs is insecure because it uses the
"--disable-hardened" flag, which disables some checks in the
VirtualBox kernel module. Since getting rid of that flag looks like
too much work, it's better to ensure that only explicitly permitted
users have access to VirtualBox.
* Drop the 666 permission on "sonypi" because it's not clear why that
device should be world-writable.

It needs udevd to be running because the modules may require
firmware. Thanks to Mathijs and Arie for pointing this out.

modprobe.
* Move the implementation of boot.kernelModules from the udev job to
the activation script. This prevents races with the udev job.
* Drop references to the "capability" kernel module, which no longer
exists.

currently, only support for fully disabling nvidia is provided, which
is helpful for saving power/heat.
In the future, this should be extended so we can choose:
- nvidia only (choose between nouveau/nvidia driver)
- IGP only
- Hybrid (choose between nouveau/nvidia driver, use the "bumblebee" package/daemon)

pierron recommended the use of types.string over mergeOptionString, as
it is superior but might break things.
For my system the change evaluated to the exactly same.

devices (because udisks doesn't remember who mounted them).
