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. Dale :-) :-)
