[yocto] A simpler way of creating an using a local kernel repository - BeagleBone example
I have had problems getting good download performance when accessing the kernels at kernel.org. Since I expect to build the kernel several times, I decided to create a copy of the kernel repository locally and use that for my builds. There are instructions on how to create a local repository in the Yocto manuals, but those are more complex than I needed. (I don't plan on checking anything into the repository.)
