Sigh. Put the reboot in a block.
    
    Podman gating tests failed:
    
       ... back_again.changed): 'dict object' has no attribute 'changed'
    
    Previous error (ignored) was a timeout in the reboot step. I have
    no idea how to fix this, so let's try putting the reboot and wait
    steps into a 'block' section and removing the '.changed'.
    
    Tested with 1minutetip. Seems to work, but the reboot was quick
    so it didn't trigger the same code.
