/dev/mem: No such file or directory

1. the two lines at the end seem like they are superfluous
2. Although useful, the dumped yaml requires editing to incorporate into a kube config file

It would be much cleaner and more useful to output only and exacltly what was needed

[evilnick]

NB the extraneous lines were caused by an error on the unit, but we should probably still filter this out?
If the output missed the kubeconfig part and dumped YAMl from one step lower we could just pipe this to a file...
