I didn't know this. This is going to break bigger things than HAL.

I wouldn't expect it, the kernel change (CONFIG_SYSFS_DEPRECATED) was
done like 2 years ago on reasonable systems.

And regarding such matches, nothing must ever use a full devpath in
any match. The parents of devices can change at any time, even during
runtime. The devpath of a device is not stable at all, and never will
be.

In this case, matching only on the <class-glue-directory>/<device
name> might be a working hack, but the only proper match would be to
check the device name and the device's subsystem, everything else is
never guaranteed to work across kernel versions.

Thanks,
Kay

Ahh, okay. Do you think Fedora should switch off CONFIG_SYSFS_DEPRECATED
by default?

If does not have that.

hal mount/unmount flash drive using dbus-send

Good day,
my goal is to mount/unmount flash drive usng hal over dbus in some program, but even using "standard"
dbus-send command for mounting/unmounting causing error message,

dbus-send --system --print-reply --dest=org.freedesktop.Hal
/org/freedesktop/Hal/devices/volume_uuid_EAEC_055A org.freedesktop.Hal.Device.Volume.Unmount

where /org/freedesktop/Hal/devices/volume_uuid_EAEC_055A is udi of my usb flash, exactly volume not device.

error

Error org.freedesktop.DBus.Error.UnknownMethod: Method "Unmount" with signature "" on interface
"org.freedesktop.Hal.Device.Volume" doesn't exist

I tried under user, under root, on debian, ubuntu.

The question is what point i've missed, or how to enable more debug output from hal or dbus?

Because according hal-spec http://people.freedesktop.org/~david/hal-spec/hal-spec.html#interface-device-volume
there are mount and unmount commands and they even throw different exceptions.

dbus-send with methods like GetProperty{String,Boolean,Integer,Double,etc} - works fine as
GetAllDevices and other stuff.

hal version 0.5.11
dbus version 1.1.20
lshal output >>>
  udi = '/org/freedesktop/Hal/devices/volume_uuid_EAEC_055A'
  block.device = '/dev/sdb1'  (string)
  block.is_volume = true  (bool)

Patch to add keycodes for OQO model 02

== I'm not on the mailing list, so please CC me on all replies. ==

Here's a patch I just threw together to get hal to recognize the OQO model 
02's keyboard. It's really just for the volume keys, as well as the video 
rotation (even though there's no Xorg driver to support randr rotation at the 
moment). 

Also, the instructions over at wiki.archlinux.org/ and 
people.freedesktop.org/~hughsient/ are superb. It made putting a patch 
together very straightforward. 

Thanks!

Please provide the output of:

lshal -lu /org/freedesktop/Hal/devices/computer | grep system | grep -v serial

It already told you everything you need to know.

You have to pass required parameters (even if they are empty). Umount 
expects array of strings.
