Hello.
It seems to me that open_warn() in tar-1.23-3.el6 package sometimes reports
EUNATCH error. I'm trying to confirm that EUNATCH really came from open() (or
its rmt versions). And I noticed that guess_seekable_archive() should preserve
the errno variable. Please consider applying this patch in upstream first.
Regards.

Subject: [PATCH] Make guess_seekable_archive() preserve the errno variable.
new_volume() in src/buffer.c calls guess_seekable_archive() which will modify
the errno variable when fstat() failed, making subsequent open_warn() report
errno by fstat() rather than errno by rmtopen().
