In my case, I didn't happen to have a root shell around, so I couldn't
fix my system while running.  I ran /lib/ld-linux-x86-64.so.2 /bin/sync
a few times, turned off the power, and booted with the kernel argument
"break=init" to get a shell in the initramfs.  From there, I remounted
/root read-write, and created the /lib64 -> lib symlink.  No rescue disk
needed.

Hope that helps,
