How to check buildah is using fuse-overlayfs or not

[BhautikChudasama]

Hi there,

I am using kubernetes hostUsers: false with buildah build --isolation chroot -t demo3 -f ./Dockerfile2. I understood chroot part but not getting where is fuse used in buildah i know about fuse.

Here is my buildah info

{
    "host": {
        "CgroupVersion": "v2",
        "Distribution": {
            "distribution": "debian",
            "version": "13"
        },
        "MemFree": 433364992,
        "MemTotal": 4006584320,
        "OCIRuntime": "runc",
        "SwapFree": 0,
        "SwapTotal": 0,
        "arch": "amd64",
        "cpus": 2,
        "hostname": "no-priv",
        "kernel": "6.12.41+deb13-cloud-amd64",
        "os": "linux",
        "rootless": true,
        "uptime": "39m 5.77s",
        "variant": ""
    },
    "store": {
        "ContainerStore": {
            "number": 1
        },
        "GraphDriverName": "overlay",
        "GraphOptions": [
            "overlay.mount_program=/usr/bin/fuse-overlayfs",
            "overlay.mount_program=/usr/bin/fuse-overlayfs"
        ],
        "GraphRoot": "/var/lib/containers/storage",
        "GraphStatus": {
            "Backing Filesystem": "overlayfs",
            "Native Overlay Diff": "false",
            "Supports d_type": "true",
            "Supports shifting": "true",
            "Supports volatile": "true",
            "Using metacopy": "false"
        },
        "ImageStore": {
            "number": 11
        },
        "RunRoot": "/run/containers/storage"
    }
}

I am not finding any difference with or without fuse.

I don't think I understand the question. The configuration appears to be set up to use fuse-overlayfs for mounting root filesystems for working containers, instead of the using the kernel's overlay filesystem.

Yes, I understand and forgot to close. Thanks.
