From 3779bae884dd0d21776e94f8a45bcd007c43d95e Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Mon, 21 Jun 2021 11:19:16 +0200 Subject: [PATCH] libimage: pull: enforce pull policy for custom platforms Enforce the pull policy to always if a custom platform is requested by the user. Some images ship with invalid platforms which we must pessimistically assume, see containers/podman/issues/10682.
