live-boot already uses rsync --progress when /bin/rsync exists; without it the copy falls back to silent cp -a. Add rsync to the ISO package list and install an initramfs-tools hook (bee-rsync) that copies the rsync binary + shared libs into the initrd via copy_exec. The hook then rebuilds the initramfs so the change takes effect in the ISO's initrd.img. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
