Review comment:
Yes, we can.
AFAIK there are two options:
* using
[hostPath](https://kubernetes.io/docs/concepts/storage/volumes/#hostpath)
* or with [Local
PersistentVolumes](https://kubernetes.io/blog/2018/04/13/local-persistent-volumes-beta/)
The first one requires the knowledge of directory names on the host.
The second one is recommended but it requires the creation of
PersistentVolumes or install a PersistentVolume provider
I am not sure what is the best approach, my current proposal is:
* Use empty dir everywhere to make it easier to start simple ozone cluster
* Provide simple option to turn on any of theses persistence (the
kubernetes files are generated and the generation can be parametrized)
* Document how to customize the kubernetes resources files
Summary: it's question of the defaults:
1. Use a complex, but persistent solution, which may not work out of the
box
2. Use a simple, but ephemeral solution (as default)
I started to use (2) but I am open to change.
