    AFAIU, Xorg uses libudev to retrieve information on devices. This
can be worked around by providing Xorg with config files like in the old
times, which is kind of a pain. This is the only thing which held me
back from switching to Mdev a few years ago.

    I have followed the development of Vdev by Jude Nelson, but, at some
point, I got frightened by the forest (dozens) of shell scrips which
implemented the actions to perform when devices were installed/removed.

    I think that, like in the case of Mdev, the biggest difficulty is in
emulating libudev, which requires in particular to maintain an
up-to-date database of devices. Jude has done a complete job and libvdev
provides this emulation, but who maintains the database ?

    Another issue with emulating libudev is that it implies to
continuously run after Udev and Systemd. I lean to think it would be
nicer to have a simpler and stable API. Though I confess I have none in
mind (~:

    Cheers.
