volume (disk) device: get rid of HAL

[sascha_silbe]

If hald is not running, the following traceback happens:

Traceback (most recent call last):
  File "/home/sugar/sugar-jhbuild/install/share/sugar/extensions/deviceicon/volume.py", line 86, in _setup_volumes
    _mount(volume, tray)
  File "/home/sugar/sugar-jhbuild/install/share/sugar/extensions/deviceicon/volume.py", line 103, in _mount
    volume.mount(gtk.MountOperation(tray.get_toplevel()), _mount_cb)
AttributeError: 'module' object has no attribute 'MountOperation'

There are several other candidates for disk hotplug detection: Fedora 11 seems to be going to use  DeviceKit-disks (which might turn out not to be much better for embedded systems, though). A udev helper script could notify Sugar as well (would need to be installed, of course).
At the very least, the exception should be catched, though.

HAL was just uninstalled again on my XO-1 because nothing except Sugar depends on it anymore. Everyone else is moving away from it; we should swim with the stream to avoid maintenance overhead. ;)
devicekit-disks is used by Gnome, so it looks like the way to go.

Agreed, though we don't use the disks part of Hal anymore. Would be good if someone could identify the replacements for the remaining uses of Hal.

OK, closing as fixed then.
