boot-directdisk: use awk instead of echo -ne for dash compatibility
PATCH 1/1 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.
