And that is why it would make sense IMHO to let the user specify special treatment for certain devices (like it is possible with udev rules (serial number, manufactor, model....)). Actually, I am asking myself if the eject command is sufficient in this case of a certain external HD device that seems to need some more commands to go into suspend mode. That's why I think it would make more sense not to hard-wire certain detach/supend/spindown commands, but make them selectable for every device. Well, just some brainstorming. :-) > Anyway, it's not a problem to do all this from the desktop level and I > just added support for this. As you seem to be a GNOME guy, I'll probably have to wait until someone starts to integrate DeviceKit support into Solid. Are you aware of any work in this direction? Thanks for your effort.
