Auto mount hard drive

[noranraskin]

After playing around a bit with my fresh bare metal install of k3os, I realised the default path for PVs is /var/lib/rancher/k3s/storage.
I wan't to save all the persistent data on an extra ssd. So I mounted a partition to that directory and changed the owner and group of storage to rancher so that pods can actually write to the file system.

However, upon a reboot all of these changes were gone. I then tried to mount the ssd and change the group+owner of storage in a run_cmd inside the config.yaml, but haven't had any success.

Setting the drive to auto mount in /etc/fstab isn't too helpful either as /etc is ephemeral.

I'm just getting into kubernetes and k3os and would love for someone to point me in the right direction.
