You are definitely not alone. Some time ago I had a need to attach my
own very simple file system to the RTEMS, and it was a real headache. My
filesystem doesn't have any support for directories, still the glue code
needs to handle all that ./.././.././ stuff itself, and it was a lot of
try-and-fix steps to get it work.
I'm sorry to say it, but I've got impression that all this eval_path
stuff is over-complicated and error-prone. Every file system implementing
./.. itself with its own bugs and misunderstandings sounds like a way to
disaster. The only reason I kept silence is my ignorance of how it could
be done more elegantly. Maybe to borrow some ideas from Linux VFS
interfaces or from FreeBSD sources?

Cool! The only question is -- is it a bug or a feature? ;)
