Tiger Lake and later Intel iGPUs need i915/tgl_guc_*.bin; without
it the i915 init wedges and floods the console. Same story on most
modern wifi/NIC hardware. Pull firmware-linux-nonfree (metapackage
covering misc-nonfree, iwlwifi, realtek, amd-graphics, …) from the
bookworm non-free-firmware repo — single line fix, ~500MB cost to
the squashfs, worth it for booting arbitrary repaired hosts.

mkosi was failing with "systemd-boot was not found at
usr/lib/systemd/boot/efi" because Bootable=yes expects systemd-boot
installed *inside* the image for EFI boot. This image is only ever
PXE-booted — iPXE loads vmlinuz+initrd from TFTP directly, so the
rootfs itself needs no bootloader.
Switching to Bootable=no drops the EFI-image assembly step; the
linux-image-amd64 postinst still creates /vmlinuz and /initrd.img
symlinks that the top-level Makefile copies into the bundle.
