From 69c459db80abece18b5557d9b8a8098a88329c28 Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Wed, 27 Feb 2013 11:00:32 +0800 Subject: discover-client: Add discover_client_boot This change implements the client side of the server-based boot interface. We add a funcion, discover_client_boot, which serialises a boot message, then sends it to the server.
