# Allow the kernel to find our wrapped modprobe (which searches
# in the right location in the Nix store for kernel modules).
# We need this when the kernel (or some module) auto-loads a
# module. This is only done at boot time to make sure that we
# don't use modules that don't match the running kernel.
# !!! We should check whether the new kernel modules are
# compatible with the running kernel so that we can upgrade
# kernel modules (e.g. the NVIDIA driver) in a running system.
