I updated my NAS box OS. It updated grub as well. I figured it would
be a good test system. All I did was this:
nas / # grub-install /dev/sda
Installing for i386-pc platform.
Installation finished. No error reported.
nas / #
I rebooted the system and it booted just fine here. According to ls,
files in ls /boot/grub/i386-pc/ were updated. They had today's date.
So, I guess it is pretty simple. Now to remember doing this. Heck,
I've never paid much attention to grub updating before.
