A bit of googling on the train this morning suggests that Adobe flash player (the old unsupported one) needs it for some reason. I'm not sure why, though--I looked at the symbol table and linkage tables of the libflashplayer.so library, and didn't see any references to libhal or even dbus. Again, my main goal with vdev is udev compatibility, not necessarily hal compatibility. If the requisite functions from hal made it into udev, then it would be something I would work on as part of vdev's release. If not, then it's outside my scope, and would be a separate project. In the mean time, it looks like someone else has done the legwork to make hal installable without breaking the things that replaced it: https://launchpad.net/~mjblenner/+archive/ubuntu/ppa-hal Hope this helps, -Jude
