I don't have the time to test this yet, but I am definitely planning on trying |
25 |
mdev. Especially because I don't like the direction udev is going. |
26 |
|
27 |
Auto-creation of /dev entries. Yes, very usefull |
28 |
Renaming devices according to some simple rules. Yes, very usefull. |
29 |
|
30 |
Auto-starting programs when a device is added. Great, when are we getting |
31 |
"autostart" support for CDs and USB-keys and under which user-account will |
32 |
these be executed? |
33 |
|
34 |
This system is mostly used by me, but my wife also uses it sometimes. Even |
35 |
when I leave a desktop-session active. She simply starts a second one. |
36 |
If this is implemented, will the autostart-script run under my account, my |
37 |
wifes, or *shudder* as root? |
38 |

Walt, keep up the good work. I need LVM to work on the server, once we have |
40 |
confirmed it does work and how to configure mdev to work with it, I'll start |
41 |
to switch my servers. |

...yet.... ;) |

52 |
That is, untill someone comes up with the "clever" idea of shoving an |
53 |
automounter into udev. (Will it then also auto-unmount when I want my CD |
54 |
back?) |
