I read your post a couple of times, and you give a pretty thorough description of what happens and some things you've tried.  But your narrative is a little confusing and so I'm not clear where you're pointing to a bug/error?

What do you mean by link and "its real name"?  A symlink? Is it a hard or a soft link?

"They found..."? Is the above the expected behavior?  What vendor?  The software provider?

This is where I got really confused.  Do you mean that after those 6 steps you expect to find a file with content of varying size?
