The idea is that / can be a very small partition and contains |
| 18 |
everything necessary to boot and administer the system, and /usr can |
| 19 |
be a separate partition or logical volume. Some advantages to this |
| 20 |
setup are: |
| 21 |
|
| 22 |
1. If the partition containing /usr is corrupted, the system will |
| 23 |
still boot, and you have enough tools (fdisk, mkfs, tar, cpio, etc) to |
| 24 |
repair and restore it. |
| 25 |
|
| 26 |
2. /usr can be on a network server. |
| 27 |
|
| 28 |
3. On the network server, exporting /usr presents no risk to /. Even |
| 29 |
if /usr is filled up, the server will continue to function and can |
| 30 |
still be administered. |
| 31 |
|
| 32 |
This is why: |
| 33 |
|
| 34 |
- command interpreters like bash, ash, etc go in /bin |
| 35 |
- network clients and remote shells (ssh, telnet, etc) go in /usr/bin |
| 36 |
- network, filesystem, and disk utilities go in /bin |
| 37 |
- large text editors (emacs, etc) go in /usr/bin |
| 38 |
- small text editors (vi, vim) go in /bin |
| 39 |
- X, KDE, Gnome, et al are in /usr |
| 40 |
- and so on... |
| 41 |
|
| 42 |
That said, you wll find a lot of desktop systems (mine included) that |
| 43 |
have / and /usr on the same filesystem. It's a matter of taste and |
| 44 |
what you will be using the system for whether you should make /usr a |
| 45 |
separate filesystem or not. |
