--device-cgroup-rule="type major:minor mode"

Add a rule to the cgroup allowed devices list. The rule is expected to be in the format specified in the Linux kernel documentation admin-guide/cgroup-v1/devices:

• type: a (all), c (char), or b (block);
• major and minor: either a number, or * for all;
• mode: a composition of r (read), w (write), and m (mknod(2)).
