Requires root?

Hello,

thanks for this interesting idea.

Trying to run the example from the readme (or any other container) fails with the following EOPNOTSUPP on fedora 42 after installing from packages:
```
$ podman run --runtime crun-vm -it --rm quay.io/containerdisks/fedora:40
Error: OCI runtime error: crun-vm: Operation not supported (os error 95)
```

Running under strace it seems to be `lsetxattr("....local/share/containers/storage/overlay/6ad90547469576bbd18732855a0d4b5d44983bf91d2cff33b70bd76e5f72c52c/merged/crun-vm-5763d9de6f0084c0f226df1df14f061ac3cc9f3e5bf99c2b129be8eac3cdf450", "security.selinux", "system_u:object_r:container_file"..., 47, 0) = -1 EOPNOTSUPP (Operation not supported)` - so selinux-related...
(I didn't try disabling selinux)

I'm just playing around and have no real need but could someone clarify what's expected here?

Thanks!
