Re: UEFI boot order, Re: Tip: Remote FAI install

Hi,

this doesn't seem to be a trivial task as the state of the boot medium 
prior to the fai installation as well as the UEFI settings for the 
single network interface both can have all kinds of states, e.g.:

(of course for production I'd disable unneeded UEFI setting, in my case 
all IPv6 and HTTP boot options, so just the IPv4 PXE boot option usually 
would be active leading to the IPv4 PXE having highest boot priority and 
then just installed HD/NVMe medium having the second boot priority)

--------
root@jammysrv:/srv/fai/config# cat hooks/partition.GRUB_EFI
#! /bin/bash

# prior to disk partioning collect the UEFI boot order
efibootmgr
