[yocto] checking out branches: tracking vs. tags

[jfabernathy]

I'm trying to understand a few git concepts as they relate to Yocto.  
Reading the 1.2 version of the Development Manual Appendix A 
(http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html#dev-manual-bsp-appendix), 
I see the statement:

   $ git checkout denzil-7.0 -b denzil


What I think this does is create me a local branch that is fixed to what 
was committed when the denzil-7.0 tag was created and it will remain 
that way and will not track the denzil branch as it gets updated.  Right????

Now if I want to track the denzil branch as changes are committed, I 
think I do the following.

  $ git checkout origin/denzil -b denzil


Now I can do git pull commands to get the updates that are committed. 
Right??
