Lab5.3 permission problems

The first podman example command fails because there's a security problem:

toastboy70@instance-lfs253-redux ~ $ podman search --filter=is-official nginx                                      
ERRO[0000] error searching registry "docker.io": error getting username and password: error reading JSON file "/home/toastboy70/.docker/config.json": open /home/toastboy70/.docker/config.json: permission denied 
ERRO[0000] error searching registry "quay.io": error getting username and password: error reading JSON file "/home/toastboy70/.docker/config.json": open /home/toastboy70/.docker/config.json: permission denied

..because the previous docker steps have us running everything as root..

toastboy70@instance-lfs253-redux ~ $ sudo ls -al /home/toastboy70/.docker/                                         
total 12

It's easily fixed by either changing the ownership of .docker or doing the podman steps with sudo, but it's really disconcerting that I'm finding so many errors in the teaching material. The testing of these steps could be automated, surely?
