The "emerge" process sometimes copies files to /var/tmp and then run it. Recent changes to images set the "noexec" flag on /var, thus preventing such activities. Temporarily clear this flag from within cros_package_to_live. BUG=none TEST=Manually set noexec on /var and run cros_package_to_live Review URL: http://codereview.chromium.org/3739001
