Convert Fedora Workstation to Fedora Server

So, you installed Fedora Workstation on your server and ended up not using the desktop environment after all and want to convert to Fedora Server without doing a re-installation? It's very easy to do:

Boot to console: systemctl set-default multi-user.target
Change identity: dnf swap fedora-release-identity-workstation.noarch fedora-release-identity-server.noarch

It might take an update of the kernel before the server calls itself "Fedora Server".

While it is possible to completely remove a desktop environment, things could break:

PeerBanHelper as Quadlet

Quadlets are available since Podman 4.4, and offer an easy way to manage container and to keep them updated!

Check podman --version.
Create /etc/containers/systemd/peerbanhelper.container with the content below:

[Unit]
Description=PeerBanHelper Container

Mounting SSHFS (SFTP) using systemd

Why use fstab when there's systemd?

# /etc/systemd/system/media-server1.mount
[Unit]
Description=Mount unit for Server1

Fedora LVM Cache for Intel Optane

Did you know that LVM has built-in support for Intel Optane? Neither did I. It's a manual configuration though and it doesn't seem to be easy to do with BTRFS, so I simply went for EXT4.

Why would you want to enable the Optane cache? It supports super low latency no matter how much you use it while the big NVMe SSD is going to get slower the busier it is.

Note: I'm talking about laptop NVMe SSDs with built-in Optane cache. Mine is a Intel® Optane™ Memory H10 32GB + Intel® QLC 3D NAND SSD 512GB, M.2 80mm PCIe 3.0, which came pre-installed in my HP Spectre x360.

To start:

Enter the UEFI and turn on ACHI for the SSD (I don't know if I did it as I forgot my UEFI password)

Globalping Probe as Quadlet

Quadlets are available since Podman 4.4, and offer an easy way to manage container and to keep them updated!

Check podman --version.
Create /etc/containers/systemd/globalping-probe.container with the content below:

# Equivalent to sudo podman run -d --cap-add=NET_RAW --network host --restart=always \
# --name globalping-probe globalping/globalping-probe
[Unit]

Web Key Directory for Proton Mail using Cloudflare Workers

Web Key Directory is a way for non-Proton users find your keys and encrypt the messages sent to you. Proton doesn't offer this for custom domains out-of-the-box, but you can proxy requests from your domain to Proton.

Create a Cloudflare Worker
Put this code in the Worker:

export default {
 async fetch(request, env, ctx) {

Proton VPN IPv6 Manual Setup

Over 80% of the servers support IPv6 but only the Linux app and the browser extension support it at the moment.

The Linux app supports IPv6 over the VPN but still connects to the VPN server using IPv4.

It's possible to make changes to the WireGuard configs that you can get from https://account.protonvpn.com/downloads to enable IPv6.

An easy way to test if a server supports IPv6 is to use the browser extension and then go to myip.wtf or test-ipv6.com.

Summary

I need macOS to test apps for macOS. I'm running Fedora Workstation F41 (latest version while writing this). I already have a Ubuntu and a Windows VM in Gnome Boxes.

Setup

Tried to follow this guide: https://github.com/kholia/OSX-KVM Some steps in the guide could be skipped for me.
