Which version of bzr do you have?  I think there's a built-in command
in latest bzr versions that shadows the one I meant.

No, it is used.  The first option has several branches under a parent
directory that is the shared repo, and stores revisions that are
common to all branches.  IOW, it's a storage optimization; e.g., when
you clone another branch, only the versions specific to that branch
will be brought downstream.

The second option is a stand-alone branch, with no repo above it.

But in both options, there's at least one branch.

My Emacs repo holds 480MB of meta-data, and I think bzr needs at least
that much to clone it.  I'd say you need 0.5GB available VM to do this
(only the first time you clone it).
