Good!

I will do it with UEFI as everybody says it is the way to go. Perhaps
the Install document should document this better in
https://cdn.netbsd.org/pub/NetBSD/NetBSD-10.0/evbarm-aarch64/INSTALL.html,
showing the different booting options.

That is a good tip, one Rpi can resurrect the other in case of hang.

Well, lighhttpd little personal web server, minidlna film server for
home. I am also thinking to use the RPi 4 to record audio from amateur
radio receivers with external USB cards (amateur radio and electronics
is my other hobby) or data from SDR network receivers. Also GPIO for
some automated tasks.

Having received several positive reviews from you and others, I  have
just ordered my new RPi4,  is coming home on thursday. I think I am
going to have fun with it!.

We'll keep in touch, I will share the experience.
Regards.
Ramiro.
