Correct. Udev itself takes over the core function of HAL, as a repository for information about hardware, and as a source of events when devices are added and removed. Other applications that previously used HAL to do this (e.g Xorg, Network Manager, Gnome/KDE) are being rewritten to use udev directly. In most cases this has already been done - my current desktop (Xorg 1.8, Gnome 2.30) no longer has HAL installed. Apart from udev, a couple of other projects provide functions that had originally been part of HAL, but didn't belong in udev. UPower (formerly DeviceKit-power) provides power management functions, and UDisks (formerly DeviceKit-disks) supports operations on disks - formatting, mounting, etc... That's the current state of things, as I understand them. If you see any mention of DeviceKit, ignore it - that was the first attempt to replace HAL, before they realised it would be easier to just merge those functions into udev. The name briefly lived on in DeviceKit-power, etc, but those projects were then renamed to UPower, etc... Simon.
