Same thing seem to work here:

  dd if=/dev/zero of=looptest bs=1M count=100 
  losetup /dev/loop0 looptest
  mkfs.ext4 /dev/loop0
  losetup -D
  echo '/root/looptest /mnt/tmp ext4 loop' >>/etc/fstab
  mount /mnt/tmp
  systemctl status mnt-tmp.mount
  mnt-tmp.mount - /mnt/tmp
          Loaded: loaded
          Active: active (mounted) since Wed, 08 Aug 2012 18:21:04 +0600; 5s ago
           Where: /mnt/tmp
            What: /dev/loop0
          CGroup: name=systemd:/system/mnt-tmp.mount

Maybe you have older systemd version (186 here), or your setup is more
complicated than that (haven't tested crypttab, but you seem to imply
that above doesn't work as well)?
