D25494: Make tar archives reproducible by setting Pax headers

bmwiedemann added a comment.


  This should work fine with a producer GNU-tar >= 1.28 , but what will be the consumer of the tar file?
  
  Asking because I remember the case of alpine Linux and its 'abuild' producer. Alpine package manager implemented its own tar and that would only be happy with
  
    --pax-option=exthdr.name=%d/PaxHeaders/%f,atime:=0,ctime:=0
  
  The other thing is about POSIXLY_CORRECT - it is only considered in recent tar git (no releases last time I checked) and only for embedding the PID of the tar process. So I would just not mention it in the commit message to make it easier to understand:
  
  > GNU tar will add ctime, atime and the PID
  >  of the tar process that created the archive
