Usando o exemplo da minha cópia do Puppet com check-out do repositório Git do upstream no Github.com ...
$ git remote show origin
* remote origin

Local branch configured for 'git pull':
master merges with remote master
Local ref configured for 'git push':
master pushes to master (up to date)
Então, se eu fosse executar o seguinte:
$ git checkout -b local_2.6 -t origin/2.6.x
Branch local_2.6 set up to track remote branch 2.6.x from origin.
Switched to a new branch 'local_2.6'
E, finalmente, execute novamente o comando git remote show origin
novamente. Eu veremos o seguinte abaixo na parte inferior:
Local branches configured for 'git pull':
local_2.6 merges with remote 2.6.x
master merges with remote master
