----------------------------------------------------------------------
  Git has been configured for FS successfully.

  pull.rebase and branch.master.rebase have been set to true

    This means that when you do a 'git pull' to fetch remote changes,
    your local changes will be rebased on top of the remote changes.
    This does NOT rewrite history on the remote FS repo, but it does
    change the commit hashes in your local tree.

    By default, 'git pull' is equivalent to running:

      git fetch && git merge origin/master

    What we've done here is change things such that 'git pull' is now
    equivalent to:

      git fetch && git rebase origin/master

    If you really want to merge rather than rebasing, run:

      git merge <commit>

    See 'man git-config' for more information.  Also see the man pages
    for git-pull, git-fetch, git-merge, and git-rebase.
