PM-1367 added support for move to right destination file after untarring from archive. This is to support flattening of files from archive into destination directory. For e.g. [  { "type": "transfer",    "linkage": "input",    "lfn": "f.c",    "id": 3,    "generate_checksum": false,    "src_urls": [      { "site_label": "cori", "url": "hpss:///hpss.tar/hpss/set2/f.c",  "priority": 100 }    ],    "dest_urls": [      { "site_label": "cori", "url": "file:///tmp/00/f.c"      }    ]  } ]

f.c is actually stored in archive in dir structure hpss/set2/f.c
