Googling to find out if it is necessary to reinstall the bootloader and update grub.cfg afer update world installed grub2 update.
I was buried in directions to install grub2, or move from old grub to grub2. But not what I wanted to know short of reading all hits word for word. So, (sniveling over), do I need to reinstall the boot loader and update grub.cfg like when it was newly installed?
