Package: cpio
Version: 2.12+dfsg-2
Followup-For: Bug #851632
Dear Maintainer,
I'm just confirming that this still occurs with the version in
experimental. Also, it appears to be completely unrelated to whether
the tarball contains "." - I've tested several variations.
Also, here's a minimal reproducer that proves that cpio can't even
handle its own output:
$ touch empty-file; echo empty-file | cpio --format=tar --create | cpio
--format=tar --list; rm empty-file
