Try harder, friend, those require granted capabilities

  $ PAGER=cat man 7 capabilities | grep -C1 MKNOD

       CAP_MKNOD (since Linux 2.4)
              Create special files using mknod(2).

  $ docker run --rm -it public.ecr.aws/docker/library/ubuntu:24.04 /usr/bin/mknod fred b 252 4
  /usr/bin/mknod: fred: Operation not permitted
