The trick is, for symlinks, ln takes the path completely literally.

So if you do
Code:
ln -s ../whatever path/to/linkname

You might expect a link to ../../../whatever, since it's more folders up, right?

Nope, it just gives a link pointing to the path ../whatever. It doesn't extend it for you.

If you give it an absolute path, it can't make this mistake.
