I don't think udev is involved when you insert CDs into a drive. Udev just has to make sure that the device node of the CD drive is created in /dev/ (normally during boot). You probably need to look into HAL (and maybe DBUS) to achieve what you want. Try to run "lshal --monitor" and insert an empty CD into the drive. Here is what I get: $ lshal --monitor Start monitoring devicelist: ------------------------------------------------- 09:38:55.289: storage_model_CDRWDVD_TS_H493A property storage.removable.media_available = true 09:38:55.313: storage_model_CDRWDVD_TS_H493A property storage.removable.media_size = 2048 (0x800) (new) 09:38:55.384: volume_empty_cd_r added <aborted with CTRL-C> I can check for the presence of (empty) removable media with hal-get-property --udi /org/freedesktop/Hal/devices/storage_model_CDRWDVD_TS_H493A --key storage.removable.media_available which returns "true" or "false", or with $ lshal --show volume_empty_cd_r volume_empty_cd_r which returns an empty string if there is no empty CD-R in the drive. (You probably also have to check for volume_empty_cd_rw to catch CD-RWs.) You could run a process which searches every few seconds for the presence of empty CD-R(W)s and runs the CD burning script if it finds one. That is probably not the most elegant way to implement it, but I think it should work. KDE offers a number of ways to interact with HAL and DBUS, so you will probably find a much nicer way to set up your CD burning kiosk if you look a bit deeper into that. -- Regards, | http://users.icfo.es/Florian.Kulzer Florian | -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
