| #!/usr/bin/env bash | |
| # This script is for Debian/Ubuntu Linux (tested on Ubuntu 22.04) | |
| # This script fixes a case of /boot/efi being installed on a mdraid (RAID1) device | |
| # That's not a supported configuration as of Grub on Ubuntu 22.04 | |
| # You have to stop and remove the mdraid, reinitialize the FAT volumes, remount /boot/efi, | |
| # then configure grub to use both devices (using debconf-set-selections), | |
| # and finally run grub reconfiguration (in this case noninteractively), which will install | |
| # grub (both EFI partitions of the former RAID1) to EFI nvram |
