RAID = Redundant Array of Independent Disks. I think this explains that it |
8 |
would be nonsense to have raid on a single disk. |

Of course, copying /dev/zero is not a good idea on a running system. You will |
20 |
wait forever for this task to finish (/dev/zero, remember there comes data |
21 |
out of it, endlessly). |

You don't have to copy anything of /dev. udev will provide you the solution to |
24 |
create a new /dev directory after boot. |
