I'm trying to figure out how to use a cloned/modified copy of the

Very strange. Is this from the yocto master branch ?
I ran this:
git clone git://git.yoctoproject.org/linux-yocto-3.0
git checkout -t origin/meta -b meta
vim
git commit

That being said. If you go into your src tree. Do you see the meta and
board branch ? Are they local branches ? Is your SRC_URI pointing at a
bare clone, and not a non-bare one ?
As you can tell from my clone command above, it is a non-bare clone
(though I have no idea what that actually means). I have lots of
branches, but aside from master only my new "meta" branch is local:
That's the problem. I have a patch that detects this and abort is a non
bare upstream is used. I just need to send them .. which I'll do when
I get back to my desk next week.
There are two reason for this bare clone requirement:
- technical: this scales to several hundred branches. cloning, and
iterating
remote branches to create local tracking branches is noisy and
time consuming. So there's a trick that has been in use for years
that you can clone a bare upstream, and mass convert the branches
to local in a single operation.
- social: you want to do your development in a different tree from the
one that is being cloned and used. That way the tree is clean, and you
are building what you expect.
This was supposed to be added to the new documentation (in the smaller,
lightened versions) .. but I don't think that is out yet.
Cheers,
Bruce
