The POSIX folks argued that ENOTDIR is not appropriate, since in _most_ contexts, symlink-to-dir/ (with the trailing slash) is indeed a directory according to the pathname resolution rules - it is only when you omit the trailing slash that it is not a directory; unfortunately, rename and rmdir have different semantics when you remove the trailing slash. But they also agreed that POSIX allows implementations to add additional restrictions on path resolution, and that as long as Linux does not violate the semantics of their interpretation of ENOTDIR (ie. uses a different errno, to make it clear that this is an intentional and addition implementation restriction of Linux), then the intuitive behavior is permissible as one of those implementation restrictions. ENOTSUP sounds reasonable, otherwise I think we'd have to invent a new one, maybe ESLASH "trailing slash on symlink"? - -- Don't work too hard, make some time for fun as well!
