I=E2=80=99m getting an impression that the above should make me feeling guilt or ashamed of sharing my workflow with the audience. But I still do not, nor see the reason to. > In addition, we've had --shared confused with --local (which is > implied anyway). FTR, in my initial message, I=E2=80=99ve indeed confused --shared with --local as the /default/ for git-clone(1), and even corrected myself [1]. I didn=E2=80=99t confuse the /effects/ of these options. > So the takeaway is not to use any options in connection with creating > local clones manually.

In this discussion, I saw no scenario under which my approach, as given in [1], would fail (but surely would appreciate any.) It wasn=E2=80=99t my intent to make claims regarding the use of --shared outside of that particular approach.
