hadori binary package in Ubuntu Focal s390x

 This might look like yet another hardlinking tool, but it is the only one
 which only memorizes one filename per inode. That results in less merory
 consumption and faster execution compared to its alternatives. Therefore
 (and because all the other names are already taken) it's called
 "HArdlinking DOne RIght".
 .
 Advantages over other hardlinking tools:
  * predictability: arguments are scanned in order, each first version is kept
  * much lower CPU and memory consumption
