[erlang-bugs] filelib:ensure_dir/1 and symlink to dir

[Danil Zagoskin]

For example, I have a directory "foo" and a symlink "bar" to "foo".
While I can access file, I get error trying to ensure_dir:
2> file:read_file("bar/baz").
{ok,<<>>}
3> filelib:ensure_dir("bar/baz").
{error,eexist}

This is because filelib:do_is_dir/2 does not expect a symlink to dir.

Is it expected behavior or should I submit a patch for that?
(This breaks at least lager which does filelib:ensure_dir before opening a
log)
