> On a unix filesystem, a file that's hard linked with multiple names has no single 'actual name'

The same is true for hard linked files on Windows. That never stops Windows from showing you a path.

There is almost always an "obviously right" path (the one used when opening the file). And if you lost track of that, deterministically choosing one of the possible paths is almost always more user friendly than just chowing inode numbers.

The path used while opening a file is easy to get confused. If your cwd changed names or was deleted since you entered it, and you open an executable with a relative path, what is the "obviously right" path then?

In context, there's still a right answer; the absolute path used to run the process should always be right, because the Windows locks the file (I'm sure with enough effort this can be made wrong, but I'm also sure that's not trivial).

Really, this discussion just shows the question is the problem; if you're asking "what path was used the launch the process", that's easy to keep track of & always be right. If you're asking "what is the path right now to the file that launched the process", maybe that has no answer.

I don't think that really follows. If the OS wants to track this, it should canonicalize the path to the executable on startup, and then stash it somewhere.

(And a program could do that itself, if it wants to.)
