I doubt we've ever checked if `mtn checkout' does anything useful when
triggered inside a freshly created new workspace, but what you've
experienced is actually by design:

mtn setup sets up a new workspace, right, but actually the use case we
think about here is that this workspace is attached to a new, not yet
existing branch.

mtn checkout on the other hand only operates and setups a workspace of
an existing branch. It completly ignores (in newer versions) the
existance of an _MTN directory and presumely needs a path parameter to
know where the checked-out files should go. So, you ask what happens if
you `mtn setup -b foo.branch foo_dir && cd foo_dir && mtn co -b
bar.branch .`? This should actually write out the checkout _MTN in
foo_dir, but will possibly complain about the fact that it already exists.

So, what are the alternatives? One could be to just use `mtn checkout`
and later change the branch name via mtn commit -b foo.branch (this puts
the old bar.branch development line under the foo.branch development
line), or you could edit _MTN/options of the checked out branch to
reflect that branch change. In any case, there is no use case here for
mtn setup...

Thomas.
