The always used example is to have /usr shared as a read only NFS |
49 |
partition among several workstations. In corporate environments it is |
50 |
certainly used this way (or at least it was when I worked, and the way |
51 |
I used it in my office seven or eight years ago). |
52 |
|
53 |
Of course, for a normal desktop user, a separate /usr is basically useless. |
