From ab7b64e9ee1e930ffe9d7f5b5eebe618a3b3a03b Mon Sep 17 00:00:00 2001 From: Peter Jones Date: Wed, 16 May 2012 13:43:26 -0400 Subject: [PATCH] x86: Don't continue booting if we can't load the specified initrd If we've determined we can't do what the user asked, trying to do something else isn't going to make the user's life better. Without this the screen scrolls a bit and then you get a panic anyway, and it's nice not to have so much scroll after the real problem in bug reports.
