N/A - Documentation Issue

---

Expected behaviour:

Documentation on Encrypted DNS via Cloudflared should use correct systemd paths, and provide update instructions.

Actual behaviour:

Documentation instructs users to update the system built-in unit store, instead of the user config store. No update instructions provided.

Steps to reproduce:

N/A - however, issues can be fixed by replacing the systemd unit /lib/systemd/system path with /etc/systemd/system/, which is the user-created store for systemd files.

Also, while this is slightly more of a documentation change request, there's no information on updating the cloudflared daemon. While not exactly elegant, something like this could be called as a cron job:

echo "Updating Cloudflared Daemon..."
wget -P /tmp https://bin.equinox.io/c/VdrWdbjqyF/cloudflared-stable-linux-arm.tgz
systemctl stop cloudflared
tar -C /opt/cloudflared -xzf /tmp/cloudflared-stable-linux-arm.tgz
systemctl start cloudflared
rm /tmp/cloudflared-stable-linux-arm.tgz
echo "Cloudflared update complete."

I was actually looking at this myself, and it seems cloudflared has a service command https://developers.cloudflare.com/argo-tunnel/reference/arguments/#service-command

So, it could be possible that the whole manual thing could be simplified nowadays.

[iUnknwn]

I submitted a small pull request that expands the docs, so a user can setup automatic updating of the cloudflared daemon. It looks like someone already updated the docs with the corrected systemd path.
