NFSv4 ACL Issue with nfs4_setfacl --test option

Issue

• When using nfs4_setfacl --test option on an NFSv4 share, the displayed ACL differs from the applied ACL:

  # nfs4_setfacl -a A::1000:RWX /path/to/share/testdir --test
  ## Test mode only - the resulting ACL for "/path/to/share/testdir":
  A::1000:rwaDxtTnNcCy
  D::OWNER@:rwaDx
  A::OWNER@:tTcCy
  A::1002:rwaDxtcy
  A::GROUP@:tcy
  A::EVERYONE@:tcy
  
  # nfs4_getfacl /path/to/share/testdir
  # file: /path/to/share/testdir
  D::OWNER@:rwaDx
  A::OWNER@:tTcCy
  A::1000:rwaDxtcy
  A::1002:rwaDxtcy
  A::GROUP@:tcy
  A::EVERYONE@:tcy
  

• Why are ACLs from nfs4_setfacl --test not the same as applied ACLs?

• Why does the nfs4_setfacl --test show different ACLs than the applied ones?
