From 364b242b70d9593e782a3d099bfc4ba04d8b3a2d Mon Sep 17 00:00:00 2001 From: Daniel J Walsh Date: Mon, 15 Nov 2021 11:48:28 -0500 Subject: Set config environment variables early in Podman init Fixes: https://github.com/containers/podman/issues/12296 [NO NEW TESTS NEEDED] because there is no easy way to test this. Tests are in containers/common.
