Actually I remember what was my motivation at the time (somewhere between 1995-1999 I think) that I decided to use a hard link. It was some trick whereby if you ran "make install" the target binary, e.g. "python1.3", was removed and then overwritten in such a way that code which was running it via "python" (a hard link to python1.3) would not be disturbed. Then a new hard link would be created atomically. But it was too clever, and it's long been replaced with a symlink. Anyway, I don't think anyone is objecting against the PEP allowing symlinks now. -- --Guido van Rossum (python.org/~guido) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
