My understanding is that sbin for system binaries, not necessarily statically linked. Normally /sbin is only in root's PATH, not normal user's. They are likely world executable, but in many cases you cannot actually run them as non-root since they usually touch things only root can access without special access (e.g. raw devices, privileged syscalls, /etc/shadow etc.). Not always though, like you can run /sbin/ifconfig as normal user in read-only mode.
