> 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.There actually *is* an easy way, in regular ls: look at the link count.It comes out of ls -l by default, and if it's >1, there will be anidentical file.I agree with the question, though: this needs to be justified (butthere may well be a justification).> 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):If you look at the patch, you'll notice that the only change is tomake the links hard links.Regards,Martin
