Absolutely NOT true, Mikkel.  You do NOT have to reinstall grub.  If
you install a new kernel, the install process builds a new initrd for
it and updates the grub menu to reflect the availability of the new
kernel, but that is NOT a reinstall of grub.

Note that grub doesn't give a toss about the initrd, but it does have to
hand it to the new kernel so the kernel can find its loadable drivers.
That's all that happens.

The only time you may have to reinstall grub is if the order of disks
your BIOS sees changes (e.g. your old sda has become sdb, etc.).
