Where do you change the the template for the root disk controller, On a running 
platform? or do I have to go to the Source code?
plugins/storage/sharedfs/storagevm/src/main/resources/conf/fsvm-init.yml 
<https://github.com/apache/cloudstack/pull/11070/files/82f2f95595a3342c4cdf457a042fa31c1167dd85#diff-4387e746a8ede4a619c5eab505714e89eb55494ff6e70c78441296f55f34d586>
