Podman adds an Error: to every error message. So starting an error message with "error" ends up being reported to the user as Error: error ... This patch removes the stutter. Also ioutil.ReadFile errors report the Path, so wrapping the err message with the path causes a stutter. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
