Review Comment:
ok, I think we can let it executed each time during bootup.
maybe add an example how to achieve one-time execution of configuration in
doc, similar to what CKS does
```
if [[ -f "/home/cloud/success" ]]; then
echo "Already provisioned!"
exit 0
fi
...
sudo touch /home/cloud/success
echo "true" > /home/cloud/success
```
I did not consider patch process, do we need to consider it ? @vishesh92
