Upgrade/update resistant local precedence directories/files

If it isn't already in Unraid's slackware OS firmware, I would very much like to have options to;

- Override config, for example for dnsmasq, ssh and possibly other services already running in the OS.

Usually this is done by using /local.d/ dirs or local.conf files that, if present, override other config files (but only for everything set in them).

That way we can -for example- change sshd config to always and only use a specific port and Ed25519 public-key signature system.

Or use dnsmasq as a LAN dns resolver (with cache) and blocking host methods, like here.

- Be able to have persistence for those config files and other additions/changes to the firmware USB-storage media content. So have them remain after upgrades/updates of Unraid.

If options to do so are already there, please point me to a wiki or docs that explain how.

Currently I'm using the /boot/config/go for this;

#!/bin/bash

cp -af /boot/config/xroot/. /root/
cp -af /boot/config/xssh/. /etc/ssh/
chmod -R 0700 /root
chmod 0600 /root/.ssh/*
chmod 0644 /etc/ssh/*

# Start the Management Utility
/usr/local/sbin/emhttp &

but I suspect there are better ways to do the same..
