I must be missing something, because I don't see how a link farm doesn't have the exact same problem.

In the case of symlinked directories we have:

  - the binary lives in /usr/bin/python3
  - /bin is a symlink to /usr/bin
  - /bin/python3 therefore refers to /usr/bin/python3

We can use either /usr/bin/python3 or /bin/python3.

In the case of a link farm we have:

  - the binary lives in /usr/bin/python3
  - /bin/python3 is a symlink to /usr/bin/python3

Again we can use either /usr/bin/python3 or /bin/python3.

As far as I can see, both methods allow insufficiently careful developers to hardcode the wrong paths. What am I missing?
