What's the purpose? Libudev provides callers with device information. This information includes all the properties of the device, which are not only stored in the udev database, but also provided by the kernel's "uevent" file. We are working on simplifying that, and udev-acl might get more efficient in the future, without the need to collect all the information, it does not really need. But for now, it's the standard libudev behavior to read the "uevent" file if asked for device information.
