# Adds rsync to the initramfs so that live-boot's toram code takes the
# rsync --progress path instead of the silent "cp -a" fallback.
#
# live-boot's 9990-toram-todisk.sh already contains:
#   if [ -x /bin/rsync ]; then
#       rsync -a --progress ... 1>/dev/console
#   else
#       cp -a ...   # no output
#   fi
#
# We install an initramfs-tools hook that calls copy_exec /usr/bin/rsync,
# which copies the binary + all shared-library dependencies into the initrd.
