After a bit of testing, the only other bug I've come across is the
renaming one that Ronald noticed when he was adding support for Solaris:
renaming a dangling symlink or a symlink that points to a directory will
fail.  The cause is that it is renamed as if it was a regular file, but
rtPathPosixRename attempts to use stat to check that it's not a

A couple of ways to fix it would be to replace stat with lstat in
rtPathPosixRename, or to add a third case throughout to treat symlinks
differently from files and directories.  I don't know which would fit in
better with the way virtualbox is organised, though.
