Larger ephemeral disk size for machines

Is there any way to allocate more ephemeral storage to a machine, right now I only see 8GB mounted on /
image
The other way would be to allocate and destroy persistent volumes but that seems like a worse idea

On another note, is it possible to make / persistent?

There’s no way to allocate more ephemeral storage currently. What’s the issue you’re having? Initially, I don’t see a problem allocating and discarding persistent volumes if you need the space.
