Arch linux not in boot menu

[Linux for blind general discussion]

Hi,

As Alexander pointed out, you don't miss anything. Let me elaborate a bit.

The Slint  installer runs grub-install which among other things writes 
an EFI OS
loader grubx64.efi in an EFI System Partition, that you can see from 
Slint as
boot/efi/EFI/slint/grubx64.efi and a boot entry in the firmware menu, 
which is
actually a link to grubx64.efi.

grubx64.efi looks for the grub configuration file grub.cfg in the /boot/grub
directory of the system from which grub-install ran (or or from the 
directory
argument of the --boot-directory option of the grub-install command).

So if you really want a boot entry for Arch in the firmware's boot menu 
you will
need to write an EFI OS loader able to boot Arch in ten EFI system 
partition, to
which this boot entry would link to. This can be done several ways, but...
Why would you need that, as long as the GRUB menu built from Slint allows to
boot Arch?

As an aside, in Slint you can run grub-emu to display the grub menu that 
will be
displayed at next boot and check the boot entries it includes.

This comes handy for blind users as the menu displayed by grub-emu is 
accessible
to the blind, but not the menu displayed when booting.

Also I am guilty of something called EFI3M
