Good question(s). |

You don't really *need* to reinstall; the old version will continue to |
| 15 |
run/boot indefinitely. |

If you want to use the new version to boot your system, you should |
| 18 |
re-run grub-install, which will copy the modules to /boot/grub and |
| 19 |
will install the core image to your MBR or EFI system partition. |

You only need to re-generate grub.cfg if you make a change to your |
| 22 |
kernel/initramfs images in /boot; your existing grub.cfg file will |
| 23 |
continue to work otherwise. |
