After the latest bootc update (1.12.0) `image-builder` and `bootc-image-builder` are failing to produce any disk images out of containers that include this new version with:

```
mount/- (org.osbuild.xfs): mounting /dev/loop0p4 -> /store/tmp/buildroot-tmp-p1p9zjbo/mounts/
mount/boot-efi (org.osbuild.fat): mounting /dev/loop0p2 -> /store/tmp/buildroot-tmp-p1p9zjbo/mounts/boot/efi
Installing image: docker://quay.io/centos-bootc/centos-bootc:stream9
error: Installing to filesystem: Verifying empty rootfs: Requiring directory contains only mount points: Found entry in boot: efi
```

This was already mentioned in matrix by @dustymaybe; but I thought an upstream issue to track this would be benificial so I can direct our users to this.

It seems there's already an open PR to address this: #1904.

As a workaround users can build containers that pin `bootc` to 1.10.0 for now.
