This commit installs crun-wasm and wasmedge-rt in the FCOS image at https://quay.io/repository/podman/fcos .

• crun-wasm is installed from rhcontainerbot/podman-next
• wasmedge-rt is installed from the official Fedora repos

Packages in Containerfile have also been rearranged in alphabetical order.

it's a good move but we still need crun-wasm and wasmedge-rt in default podman machines (here it requires a podman machine os apply and only 'next' releases of podman are available (not the tags)

[rhatdan]

We need to move to a podman-machine where this happens automatically.

@benoitf @rhatdan sorry I'm gonna need some dumbing down to understand your comments. Machine terminology is quite unfamiliar to me.

rpm-ostree has a mechanism for updating from an OCI image like this. It would be nice to get to the point that we have a standard FCOS image set to point at an OCI Image with additional packages, and then install them as a layer on top of FCOS. They we would not need to beg from FCOS to add additional packages for Podman Machine.

[lsm5]

Given the recent fcos agreement, do we still need this even if temporarily? I'll need to repurpose this anyway to get crun-wasm from podman-next, even if it's just a symlink for now.

[rhatdan]

I think we need to work on the layering concept and complete it. I don't think we should be going to fcos any longer for additional packages. We need to get podman-machine to update from OCI Images like this one.
