Raspberry Pi 4 can finally boot directly from USB

Can you host the netboot server from a workstation by chance? This is something I had never considered and it would really change things up for me, how does that even work? Is it just an installed distro or just a network image on the device it's booting from? I'm somewhat familiar with netbooting an installer but I've never setup a server just used the tech to install an OS from the network to hardware.

I did bump into these docs:

Are these the gist of it, or did you do a little more?

Well, that's instructions on how to setup a Pi itself to be the netboot server. That will work fine, but your DHCP server still needs to be configurable to emit the correct responses to find the TFTP server, if you don't want to use a Pi itself as your DHCP server, which I would imagine most people don't.

My DHCP server is pfSense, and I'm using a FreeNAS server as the TFTP/NFS server.

The Pi netboot procedure is documented in more general terms, here: https://www.raspberrypi.org/documentation/hardware/raspberry...

Why wouldn'y you? That's what I do: I use the DHCP server (dnsmasq) that comes with pi-hole, with a few additional config files, and it works pretty well. It even grants leases faster than my router was (which has been an issue for radv packets & DNS).

Pi notwithstanding, it feels like this process hasn’t changed in 30 years.

I know for a start Microsoft made some ‘updates to the standards’ when they found out tftp isn’t really suitable for fetching gigabyte size images.
