I could reproduce your results with a patched dracut:

```
$ lsinitrd /boot/initrd.img-6.19.11+deb14-amd64
[...]
dracut cmdline:
 root=/dev/mapper/loop77p2 rootfstype=ext4 rootflags=rw,relatime
```

But I verified in a chroot that the patch works as intended
(hostonly_cmdline is enabled before but disabled with the patch).

We need to further investigate what went wrong in your example. At least
I see "Version: dracut-110-9" in the lsinitrd output. So the initrd was
regenerated after the package update.
