From: "Avery, Brian" <b.avery@hp.com>
I passed init=/mylinuxrc to the kernel on the command line. The kernel
silently dropped down to exec /sbin/init. It turned out that /mylinuxrc
had improper permissions. Without any warning message from the kernel that
something was wrong it took awhile to find the issue. The patch below adds
a warning.
