sceKernelRmdir, and rmdir through it, checked the path with
std::filesystem::is_directory and is_empty, which follow a symbolic
link, and then removed the path itself. So rmdir on a link to an empty
directory returned 0 and deleted the link, while the target stayed.
FreeBSD looks up the last component of rmdir's path without following
it (sys/kern/vfs_syscalls.c, kern_rmdirat: NDINIT_ATRIGHTS with
LOCKPARENT | LOCKLEAF and no FOLLOW) and then fails with ENOTDIR for
anything that is not a directory: "if (vp->v_type != VDIR) { error =
ENOTDIR; goto out; }". A link, whether it points to a directory or
nowhere, is a VLNK there.
rmdir now returns ENOTDIR for a symbolic link and leaves it alone, as
unlink already looks at the link itself through symlink_status. A
trailing slash still resolves through the link, as before.
