Dear Maintainer,
After the upgrade to bookworm starting ephemeral container with lxc-copy
command always fails with an error:

The problem seems to be in the container value of bdev_type that is not
initialized properly for the overlay case. The following simple patch is
probably not the correct fix but it shows that rootfs->bdev_type is NULL
and if initalized properly the container starts up correctly.
