Subject: [meta-oe][PATCH] mkefidisk.sh: add boot log on console
Date: Sat, 28 Nov 2015 09:29:51 -0500	[thread overview]
Message-ID: <1448720991-29707-1-git-send-email-twoerner@gmail.com> (raw)

Hooking up a serial console is a "developer mode", the chances are pretty good
developers are interested in watching the kernel boot log on the console so
they can spot any problems or diagnose any failed boots (e.g. can't find root
fs).
