Why hard links? Symlinks are much more introspectable. When looking at a hard link I have no easy way to know it's the same as whatever other file in the same directory. I also don't understand this mention: “The make install command in the CPython 3.x series will similarly install the python3.x, idle3.x, pydoc3.x, and python3.x-config binaries (with appropriate x), and python3, idle3, pydoc3, and python3-config as hard links. This feature will first appear in CPython 3.3.” This feature actually exists in 3.2 (but with a symlink, fortunately): $ ls -la ~/opt/bin/pydoc3 lrwxrwxrwx 1 antoine antoine 8 oct. 15 21:24 /home/antoine/opt/bin/pydoc3 -> pydoc3.2* Regards Antoine. _______________________________________________ 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
