From b9313d355e8cd6307d8772ad9c21958ffe981e5b Mon Sep 17 00:00:00 2001 From: Nalin Dahyabhai Date: Wed, 16 Oct 2019 11:57:45 -0400 Subject: pull/create: add --override-arch/--override-os flags Add --override-arch and --override-os as hidden flags, in line with the global flag names that skopeo uses, so that we can test behavior around manifest lists without having to conditionalize more of it by arch.
