Writing the primary GPT before the backup may lead to a confusing situation: booting a freshly updated system could consistently fail and next boot will fall back to the old system if writing the primary works but writing the backup fails. If the backup is written first and fails the primary is left in the old state so the next boot will re-try and possibly fail in the exact same way. Making that repeatable should make it easier for users to identify the error. Additionally if the firmware and OS disagree on the disk size, making the backup inaccessible to GRUB, then just skip writing the backup. When this happens the automatic call to `coreos-setgoodroot` after boot will take care of repairing the backup. |

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
