It's a bind mount, not a regular mount. A regular mount takes a |
| 13 |
volume/block device/whatever and mounts it somewhere. |

A bind mount makes a copied mount that is already present on your system |
| 16 |
and makes it also available somewhere else. |

You do not want /dev/ and /sys mounted twice - they are core system |
| 19 |
directories and bad things can happen if you mount them twice then |
| 20 |
change one of them. You get sync issues for one thing. Much much easier |
| 21 |
to use bind mounts and potential problems just go away |

The handbook says to do it, and it makes sense to do it. |
| 28 |
|
| 29 |
Any tutorial that doesn't say it, is wrong/outdated or it's author |
| 30 |
doesn't understand. |
| 31 |
|
| 32 |
If the official handbook says to do it, and some other post from Joe |
| 33 |
Random Blogger says not to, which one you gonna believe? |
