     221For automatically resizing the rootfs on boot you can create a one-shot init script before you unmount the filesystem above:
     222{{{#!bash
     223cat << EOF > /etc/init.d/resize2fs_once
     224#!/bin/sh
     225### BEGIN INIT INFO
     226# Provides:          resize2fs_once
     227# Required-Start:
     228# Required-Stop:
     229# Default-Start: 2 3 4 5 S
     230# Default-Stop:
     231# Short-Description: Resize the root filesystem to fill partition
     232# Description:
     233### END INIT INFO

     237ROOT=\$(cat /proc/cmdline | sed -e 's/^.*root=//' -e 's/ .*\$//')
     238
     239case "\$1" in
     240  start)
     241    log_daemon_msg "Starting resize2fs_once" &&
     242    resize2fs \$ROOT &&
     243    rm /etc/init.d/resize2fs_once &&
     244    update-rc.d resize2fs_once remove &&
     245    log_end_msg \$?
     246    ;;
     247  *)
     248    echo "Usage: \$0 start" >&2
     249    exit 3
     250    ;;
     251esac

     254chmod +x /etc/init.d/resize2fs_once
