+cat << EOF > /etc/init.d/resize2fs_once
+#!/bin/sh
+### BEGIN INIT INFO
+# Provides:          resize2fs_once
+# Required-Start:

+# Description:
+### END INIT INFO

+    log_daemon_msg "Starting resize2fs_once" &&
+    resize2fs \$ROOT &&
+    rm /etc/init.d/resize2fs_once &&
+    update-rc.d resize2fs_once remove &&
+    log_end_msg \$?
