Updating NetBSD system files on a Raspberry Pi Zero W with the 'sysupgrade' utility requires a small edit to /usr/pkg/etc/sysupgrade.conf: RELEASEDIR="https://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-$(uname -r | cut -d. -f1)/latest/$(uname -m)-$(uname -p)" This changes part of the subdir from "evbarm" (which doesn't exist) to "evbarm-earmv6hf" (which does). Please note that I might not know what I'm doing, being quite new to NetBSD. #NetBSD #RaspberryPi
