Gnome (and most other desktop environments) can be configured to auto-mount a |
37 |
USB-drive, CDs,... |
38 |
|
39 |
Gnome will, as is mentioned previously, probably use "pmount" started as the |
40 |
current user which will then mount the drive with the user as the owner. |
41 |
|
42 |
udev-rules are only really needed when you don't (want to) use an automounter |
43 |
with your X-desktop. |

I myself use KDE and there I can specify if I want a USB-drive mounted or not. |
46 |
I believe I can also specify some USB-drives to auto-mount when I plug them |
47 |
in. But I do prefer to be able to decide each time as sometimes I just plug in |
48 |
my phone or camera to charge it. (My phone also acts like a usb-drive when so |
49 |
configured) |
