I never said it was hard; but someone or something has to do it. |

You don't remember /dev ca. 2002 or 2003? It was a mess. |

Again, the important problem (the *interesting* problem), is to solve |
25 |
the general case. That means having nodes for *all* possible hardware |
26 |
out there, in *all* possible combinations. |

|
28 |
Of course every single user can keep a neat and clean /dev directory. |
29 |
The point is, most users don't want to do that. Using udev solves that |
30 |
issue *for every possible user using every possible hardware |
31 |
combination*. |
