`bootc` install doesn't work with `skopeo` `docker-daemon://` source-imgrefs

[eadwu]

Not sure exactly why, all of this is running within a container with bootc and all directories necessary are mapped to the container because running skopeo manually works fine.

This works fine

skopeo copy docker-daemon:bootc:latest oci-archive:/output/bootc.tar:bootc:latest
bootc install to-disk --disable-selinux --composefs-backend --allow-missing-verity --bootloader systemd \
    --via-loopback /output/bootable.img --filesystem ext4 --wipe \
    --source-imgref oci-archive:/output/bootc.tar:bootc:latest \
    --karg console=tty0 --karg console=ttyS0,115200 --karg selinux=0

This fails

bootc install to-disk --disable-selinux --composefs-backend --allow-missing-verity --bootloader systemd \
    --via-loopback /output/bootable.img --filesystem ext4 --wipe \
    --source-imgref docker-daemon:bootc:latest \
    --karg console=tty0 --karg console=ttyS0,115200 --karg selinux=0

with

error: Installing to disk: Getting container info: failed to invoke method GetBlob: Unknown blob sha256:529a7c28bf7fe83341ce9296a990df37a497e58a900cbedccdd814b6a52d6a45

So I'm assuming it is a bootc issue. Docker registry works (docker://ghcr.io/jmarrero/ubuntu-bootc:latest) but not docker-daemon.

The following are bind mounted

    -v /var/lib/docker:/var/lib/docker \
    -v /var/lib/containerd:/var/lib/containerd \
    -v /var/run/docker.sock:/var/run/docker.sock \
