From 6f9d9986d54cb53e50b33a044a9c89572736d96a Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Mon, 5 Dec 2011 12:09:27 +0000 Subject: [PATCH] x86: Add support for specifying an initrd with the zboot command This change finishes plumbing the initrd support built into the zboot mechanism out to the command interface. It also fixes a bug in the command declaration where the kernel size could be passed as an optional second parameter but not enough arguments were allowed.
