The Nvidia GL driver seems to get a little confused when the /dev/nvidia* permissions aren't quite what it expects due to user namespaces — e.g., trying to shell out to nvidia-modprobe — and we've had problems in the past with it trying to mknod() the devices when they (apparently?) don't exist. And now it's trying to chown() something; this isn't happening for me, but I'm seeing it crash-stats. It's simple enough to fail with EPERM.
