bootc install to-filesystem - having issues with passphrase LUKS

Hello, I'm trying to install bootc on top of an existing system that's configured with a LUKS passphrase. Reproducing this is easy, just a standard CentOS Stream 9 install - check the box for encryption during installation. Then run the bootc deployment method I describe below on top of the newly installed system. When the system reboot it hangs for a while then drops to a dracut prompt. No interesting log messages as far as I can tell.

I've looked/searched through all the bootc documentation and all of the issues & discussions on GitHub, but I cant seem to find any examples or anyone talking about using regular passphrase LUKS with this bootc deployment method.

Is this a known issue or am I doing something wrong? Thanks for your time.

I am using this deployment method as a test:
```
podman run --rm --privileged \
--pid=host --security-opt label=type:unconfined_t \
--volume /dev:/dev \
--volume /var/lib/containers:/var/lib/containers \
--volume /:/target \
--entrypoint bootc \
quay.io/centos-bootc/centos-bootc:stream9 \
install to-filesystem --skip-fetch-check --replace=alongside /target --root-ssh-authorized-keys /target/root/.ssh/authorized_keys
```

Reproduce the failure with a standard CentOS Stream 9 installation using passphrase LUKS, then run the provided `bootc install to-filesystem` command and observe the reboot and dracut prompt. Start by checking the bootc deployment behavior and available dracut logs; done means the installed system reboots successfully and accepts the LUKS passphrase.
