From a4c24719445777292193fa2c7a325a1757096fdd Mon Sep 17 00:00:00 2001
From: Ed Santiago <santiago@redhat.com>

Subject: system tests: various

- images: confirm that 'podman images' emits headings
  even if there are no images present. Intended to
  replace e2e test which is difficult to get working
  under podman-remote.

- build: add test for #8092, podman-build gobbling stdin.
  Workaround needed for issues #8342 and #8343, in which
  podman-remote output differs from podman local.

- volumes: add test for #8307, double-lock on same volume.
