[yocto] Git tool/command problems with YOCTO Open Source repos

[Burton, Ross]

Personally I don't see why there needs to be One Blessed Tool to
manage keeping repositories in sync.  There's lots of alternatives,
none of them is obviously superior to the others, and none of them
have any requirements on the repositories that they're managing.

If you want a repository management tool, then pick one and use it.
