Comment 2 for bug 434362

Ha, I have a smoking gun. This cannot possibly be a GRUB bug; GRUB's cursor doesn't blink! The blinking cursor is set up by the kernel when it initialises the console.

We could turn it off in the initramfs, but there's probably some noticeable time between console initialisation and initramfs entry. If we want the cursor to be invisible at boot, then it will *have* to be done in the kernel, perhaps conditional on the "quiet" command-line argument. Something will need to take care of turning it back on once the system is up, though, as it will look rather odd otherwise.
