Reference

There are many good articles out there

There are some great (?) tutorials out there describing the same topic, and of course this one compiled with their help.

Why this tutorial is better than

• https://ubuntu.com/server/docs/install/netboot-arm64 - this tutorial is covering UEFI boot explaining where to het shimx64.efi and grubx64.efu, but it's missing all DHCP and TFTP configuration moments.

• TecMint - very descriptive, but here we use Debian's package manager

• Debian's wiki - focuses more on DHCP configuration, but we also add NFS server and make very nice boot menu

• Red Hat - probably works great on Red Hat Linux, but I like free and open source solutions. So in this tutorial we configure completely different packages
