Perhaps it would help if you for a minute try to break the assumed and |
| 30 |
transparent (from a M$Windoze user perspective) linkage between |
| 31 |
filesystem components (e.g. a directory like /mnt/gentoo) and device |
| 32 |
components (e.g. a partition like /dev/hda3). The physical device which |
| 33 |
contains actual data will only be connected to the software entity of a |
| 34 |
directory, after it is mounted (linked) to it by means of # mount |
| 35 |
<device> <path>. After that linkage (mounting) is established your OS |
| 36 |
can access and read the data stored on that device. |

Not as you understand it: directories are software entities, /dev/hda3 |
| 44 |
is a physical device (hardware). In other words, you are creating a |
| 45 |
subdirectory within your /mnt/gentoo directory - a software path in your |
| 46 |
filesystem. As long as your /mnt/gentoo directory has been linked to |
| 47 |
the physical device of /dev/hda3 then this |
| 48 |
<directory/subdirectory/.../files> structure and its contents will be |
| 49 |
stored (saved) in the mounted /dev/hda3. |

OK, if you were to mount your /dev/hda4 to your /mnt/gentoo/usr then any |
| 55 |
relevant data produced thereafter will no longer be stored on the |
| 56 |
previously mounted device (/dev/hda3), but on the newly mounted |
| 57 |
/dev/hda4. |

I hope this helps. |
