can you just include chromeos-common.sh to get this?

then you can just simplify this to making sure $GPT is set

+# chroot, but some of these functions may be invoked outside the chroot (by
+# image_to_usb or similar), so we need to find it.
+GPT=$(which gpt 2>/dev/null) || /bin/true
+if [ -z "$GPT" ]; then
+  if [ -x "${DEFAULT_CHROOT_DIR:-}/usr/bin/gpt" ]; then
+    GPT="${DEFAULT_CHROOT_DIR:-}/usr/bin/gpt"
+  else
+    echo "can't find gpt tool" 1>&2
+    exit 1
+  fi

perhaps say, "File generated by emit_gpt_scripts.sh. Do not edit."
