archiso keeps vmlinuz/initramfs in the ISO boot dir, not the squashfs, so unpackfs lays down an empty /boot. The chroot's mkinitcpio/grub-mkconfig had nothing to work with and the ESP ended up empty (firmware found no bootloader). - shellprocess@kernel (dontChroot) copies the live kernel into the target /boot before the bootloader step - post-install.sh now runs grub-install itself, including a --removable pass so firmware with no NVRAM entry still boots via EFI/BOOT/BOOTX64.EFI Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
