From 9af6ba1b77f4b9572b8256889e1703b74a839576 Mon Sep 17 00:00:00 2001 From: Mandeep Singh Baines Date: Thu, 13 Jan 2011 15:45:42 -0800 Subject: [PATCH 1/4] run_remote_test.sh: explicitly start/stop ssh-agent run_remote_test.sh is implicitly depending on remote_access.sh to setup the ssh-agent for it. This broke when I tried to remove ssh-agent starting from remote-access.sh. Implicitly dependencies are ugly. BUG=n0ne TEST=Ran a test on my local machine. Tested with and without default board.
