I will be wikifying this later, but I've gotten this partially tested and working while installing my Challenge S. As of the writing, I've tested:

RSH - WORKS
TFTP - WORKS
BOOTP - WORKS

Still working on bootp because I installed IRIX on a challenge and circumvented having to use an AUI transceiver by  use of a CD boot into the miniroot, where the mezzanine NIC works. 

Various config files:

Code:

root@zelan /netboot % cat /etc/inetd.conf | egrep -v "#"
shell           stream  tcp     nowait  root    /usr/libexec/rshd       rshd -L
tftp            dgram   udp     wait    root    /usr/libexec/tftpd      tftpd -l -s /netboot
bootps          dgram   udp     wait    root    /usr/sbin/bootpd        bootpd -d 4 -t 120
root@zelan /netboot % cat /etc/hosts | egrep -v "#"
::1                     localhost localhost.
127.0.0.1               localhost localhost.
192.168.1.96            zelan zelan.projectkitsune.local
192.168.1.125           challenge
root@zelan /netboot % cat /etc/passwd | egrep guest
operator:*:2:5:System &:/usr/guest/operator:/sbin/nologin
guest:*:1001:20::/usr/people/guest:/bin/sh
root@zelan /netboot % cat /usr/people/guest/.rhosts
challenge root

Let me answer some questions:

1. Will you release detailed instructions?

Already on it

2. Will you be willing to help script this?

Of course. 

3. What environment are you using? 

Zelan is running NetBSD 9-CURRENT and is an RPi3B (not a plus) that has a 64G SD card

4. Would you give me your RPi image?

I may do an RPi image eventually, but I'm far from an expert here, so I may need to wait for a person a  bit smarter and more dedicated to look into that. 

Overall, I've done net installs on FreeBSD, Solaris/illumos and NetBSD. NetBSD has been by far the easiest to get working, thus far. I did cancel my little IN-BSD thing simply due to lack of interest. I may pick it back up if someone really wants me to, but I'm trying to avoid  burnout again.

bootp does indeed work. It took me a bit due to lack of documentation on netbsd, but the config was updated above. 

For /etc/bootptab, this entry works:

Code:

hrimfaxi:ip=192.168.1.122

This was an example for me. You only need a hostname and ip, generally, in that format. 

The other things to note:

Your NetBSD box must have a static IP/gateway
Your hostname must resolve in /etc/hosts. For me, that's:

zelan.projectkitsune.local

with IP 192.168.1.96
