>Objet : [Buildroot] [PATCH 05/14 v4] package/eudev: split udev/libudev
>
>Quite a few packages are happy with just libudev, and not a full udev daemon
>running.
>
>Split the eudev package so that we can install just libudev if /dev management
>is not handled by eudev.
>
>When only the library is installed, behave as a provider for the libudev virtual
>package. If /dev management is handled by eudev, then also be a provider for
>the udev virtual package.
>
>Adjust comments of dependencies accordingly.
>
>Note:
>    Most of the .mk splitting of the dependencies and the build/install
>    rules are from Bernd. Thanks! :-)
