Using ostree

[MR ZenWiz]

In my latest work, I need to set up a system that runs *buntu within
an ostree context.

I've looked aounrd in Google and can't find a good reference for how to do this.

I want to install Ubuntu 20.04 in a VM, then convert it to use ostree
for system-boot management.

Any suggestions?

I'm reading the ostree manual, but it is fairly lengthy and I haven't
seen what Ineed for this yet.

Many thanks.
