Arch, Ubuntu: So what's the deal with libudev.so.0?

I'm interested in building Linux desktop apps with Web front-end technologies. Both platforms I've tried -- [Chromium Embedded Framework](https://code.google.com/p/chromiumembedded/)/[CEFPython](https://code.google.com/p/cefpython/) , and [Awesomium](http://www.awesomium.com/) , seem to have a dependency on libudev.so.0, and fail in a most unpleasant manner when they don't find it. libudev.so.0, however, doesn't seem to be provided by any package in recent Ubuntu releases, and this [AUR package](https://aur.archlinux.org/packages/libudev.so.0/) only implements the common, yet controversial fix of symlinking it to libudev.so.1. On the other hand, the Chromium browser, on a recent version of which both CEF and Awesomium are based, runs happily without that dependency. Does anyone know what's the story behind this library? And how do I properly ensure reliable operation across different Linux distros for software that relies on embedding Chromium?
