SunOS-3/4 (a BSD 4.x derivative) allowed them, but restricted them to root. It did not handle the issue of '..' at all, and if you did much of anything at all with the directory while the "extra" link was present (which meant the filesystem was no longer a tree) it didn't go well. It wasn't something you did a second time. -- Grant -- https://mail.python.org/mailman/listinfo/python-list
