New: - podman exec - podman load (requires #2674) - CLI parsing (regression test for #2574) Improved: - help: test "podman NoSuchCommand", and subcommands - help: test "podman cmd" without required args - pod: start with --infra=false; this allows running rootless - log: also run 'logs' after container is run - log: test -f with two containers Also, use helpful descriptions for skip_if_rootless Tested on f29, root and rootless. As soon as podman-remote supports rm, I'll start testing that too. Signed-off-by: Ed Santiago <santiago@redhat.com>
