I don't know how much of an impact it will have directly here, but please be aware that there are some differences in the way the system handles symlinks ...

The most important differences are:

- Symbolic links don't "follow" files if they get moved - they reference
a specific location on the hard disk, or a specific path relative to
themselves (depending on how they're created)


- Aliases aren't resolved by POSIX system calls - they just look like files
with weird data in them.


Pick your poison.

There's also at least one bug in the way the API interacts with symlinks. If you have an alias - not a Finder alias file, but an in- memory alias record - that references a symlink, resolving the alias will by default end up pointing at the file the symlink references rather than the file system entry for the link itself. When an alias references a Finder alias file, resolving it correctly gives you the alias file. But we're drifting OT for this list now.
