file-permissions

问题 I have a problem, that I cannot grasp at all. I'm running my Jenkins pipeline in a Docker container on the master node. Now I added another node and want to run the pipeline there as well.

I can connect via shell and type root@android:/ # su root@android:/ # cd /dev root@android:/dev # chmod 666 video4 and it works. But each time I disconnect the camera, and reconnect it, I have to do it again. Via shell I can remount the root file system r/w mount -o rw,remount -t rootfs rootfs / and
