Thanks. I will start to review Chapter 7 soon. I know that it is out of

No I haven't. If those are created automatically in the devtmpfs code
then we don't need them, but I'd want to verify that in the code. I'd
thing that is somewhere in the kernel. I'll try to find something.
I don't have any of these in that

You're right about the mknod as an unprivileged user. Any suggestions?
I suppose there could be something like:
NULLDEV = /lib/udev/devices/null
if [ $EUID == 0 && ! -e $NULLDEV ]; then mknod -m666 $NULLDEV c 1 3; fi
