From adcb8fefb07484d157762706ac9ba46fe22577b4 Mon Sep 17 00:00:00 2001 From: Jonathan Liu Date: Sat, 20 Jul 2013 22:11:20 +1000 Subject: [PATCH] boot-directdisk: use awk instead of echo -ne for dash compatibility The echo command is a dash shell built-in and does not support the -n and -e options so use awk instead. This fixes the partition table being corrupted when writing the MBR disk signature into the image.
