this doesn't work, do you mean: 
+		block=$(awk "/^${root}/{print substr(\$6, 1, 3); exit}" \

? 

In my setup update-initramfs also checks the root partition to find out which 
boot loader is used (/usr/sbin/update-initramfs mbr_check() in line 188ff). 

After changing both lines update-initramfs works, but the nas is dead after 
reboot. Good time to test the recovery mode;)
