Describe the bug

whiteouts do not seem to work building on a tmpfs.
I saw this when trying to run the 'dir whiteouts work' test in test/dir-whiteout.bats on a tmpfs.

The following stacker.yaml

base:
    from:
        type: docker
        # url: oci:/tmp/sync-oci.d:busybox:latest
        url: docker://busybox:latest
    run: |
        mkdir /foo
        touch /foo/bar
mid:
    build_only: true
    from:
        type: built
        tag: base
    run: |
        rm -f /foo/bar
        rm -Rf /foo

I'm in a dir that is on a tmpfs.

$ df -h .
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           128G   13M  128G   1% /mnt/tmpfs

$ grep /mnt/tmpfs /proc/1/mountinfo 
1898 28 0:97 / /mnt/tmpfs rw,relatime shared:34 - tmpfs tmpfs rw,size=201326592k,inode64
856 1898 0:113 / /mnt/tmpfs rw,relatime shared:464 - tmpfs tmpfs rw,size=134217728k,inode64

$ uname -r
6.2.0-31-generic

Running 'stacker build' produces:

$ stacker build
preparing image base...

Copying config 5ed23df91f done

+ rm -f /foo/bar
+ rm -Rf /foo
rm: can't remove '/foo': Input/output error
error: run commands failed: execute failed: exit status 1
error: exit status 1

It fails the same way privileged (via sudo).

It generates some dmesg output

$ dmesg | tail
[7867619.584151] overlayfs: failed to set xattr on upper
[7867619.584158] overlayfs: ...falling back to xino=off.
