Currently the situation is a bit strange, because while git-remote supports selecting which branch is meant to be remote-tracking master branch via '-m <master>' option to "add" subcommand (setting origin/HEAD symref), git-clone which is init + remote + fetch + some bookkeeping and shortcuts doesn't.

Both commands are now built-in.

You can use (with new anough Git)

  $ git checkout --track -b master origin/master

to setup repository in such way that "git pull" on 'master' would know that it is meant to fetch from 'origin' and merge 'origin/master'.

In upcoming 1.6.1 it would be enough to use

  $ git checkout --track origin/master
