Re: ubuntu?

je me suis bidouillé un petit script python qui se connecte a HAL via DBUS et qui utilise pmount pour monter les clefs usb et les cdrom.
c'est en grande partie repompé de hal-device-manager
et il faut parfois utiliser pumount a la main pour demonter.
en attendant une vraie integration dans kde (deja dans le CVS je crois)...
