in order to use darktable with OpenCL everytime before starting darktable I have to issue
sudo modprobe nvidia-uvm sudo mknod -m 666 /dev/nvidia-uvm c 250 0 What is the right way to enable nvidia-uvm by default?

Proper way to do this is described in CUDA documentation:
Script from link above:
#!/bin/bash /sbin/modprobe nvidia if [ "$?" -eq 0 ]; then # Count the number of NVIDIA controllers found. NVDEVS=`lspci | grep -i NVIDIA` N3D=`echo "$NVDEVS" | grep "3D controller" | wc -l` NVGA=`echo "$NVDEVS" | grep "VGA compatible controller" | wc -l` N=`expr $N3D + $NVGA - 1` for i in `seq 0 $N`; do mknod -m 666 /dev/nvidia$i c 195 $i done mknod -m 666 /dev/nvidiactl c 195 255 else exit 1 fi /sbin/modprobe nvidia-uvm if [ "$?" -eq 0 ]; then # Find out the major device number used by the nvidia-uvm driver D=`grep nvidia-uvm /proc/devices | awk '{print $1}'` mknod -m 666 /dev/nvidia-uvm c $D 0 else exit 1 fi
