Hello!

I backported systemd 208 (including udev, of course), from Utopic, to
Trusty.

Take a look: https://launchpad.net/~martinx/+archive/ubuntu/systemd

You can try it on Trusty by running:

sudo add-apt-repository ppa:martinx/systemd
sudo apt-get update
sudo apt-get dist-upgrade

Hoe it helps!

Let us know if it works for you!   :-)

Cheers!
Thiago
