Deploying a Dual-Boot Multi-Disk Image¶
If you create a Multi-Disk image with a dual boot configuration, the efi
boot entries will not be maintained automatically when deployed to
different hardware
To Fix this you should create a post-install script to handle it

Post-Install Script¶
Post install scripts can be added on the fog server at
/images/post-install
You need to use efibootmgr in a post script to configure the efi boot
entries and maintain your dual boot config
` efibootmgr -c -d /dev/nvme0n1 -p 1 -L "Debian" -l "\EFI\debian\shimx64.efi"
`
