 A few more words on always quoting the variables: For the sake of consistency (and for making ShellCheck happy), I am not against quoting everything I encounter. I also think that the larger the Bash script becomes, the more critical it becomes always to quote variables. That's because it will be more likely that you might not remember that some of the functions don't work on values with spaces in them, for example. It's just that I won't quote everything in every small script I write.

 I can't entirely agree here. The external commands (especially sed) are much more sophisticated and powerful than the built-in Bash versions. Sed can do much more than the Bash can ever do by itself when it comes to text manipulation (the name "sed" stands for streaming editor, after all).

 This way, the script could grow far beyond 1000 lines of code and still be maintainable. With more features, execution speed may slowly become a problem, though. I already notice that Gemtexter doesn't produce results instantly but requires few seconds of runtime already. That's not a problem yet, though.

 Remember: For that to work, you have to make sure that DTail supports your log format. You can either use the ones already defined in internal/mapr/logformat or add an extension to support a custom log format. The example here works out of the box though, as DTail understands its own log format already.

 There is a lot going on here. Let's have a detailed look at what it is doing. As a note, the function relies on GNU Date, so MacOS is looking for the gdate commands to be available. Otherwise, it will fall back to date. You need to install GNU Date for Mac, as it isn't installed by default there. As I use Fedora Linux on my personal Laptop and a MacBook for work, I have to make it work for both.

 The cleanup function kills all open Tmux sessions that haven't been renamed properly yet—but only if they aren't attached (e.g., don't run in the foreground in any terminal). Cleaning them up automatically keeps my Tmux sessions as neat and tidy as possible.

 If no session is specified (as the argument of the function), it will try to attach to the first open session. If no Tmux server is running, it will create a new one with tmux::new. Otherwise, with a session name given as the argument, it will attach to it. If unsuccessful (e.g., the session doesn't exist), it will be created and attached to.

 All it does is list all currently open sessions in fzf, where one of them can be searched and selected through fuzzy find, and then either switch (if already inside a session) to the other session or attach to the other session (if not yet in Tmux).

 This function is just a wrapper around the more complex tmux::tssh_from_file and tmux::tssh_from_argument functions, as you have learned already. Most of the magic happens there.

 It expects at least two arguments. The first argument is the session name to create for the clustered SSH session. All other arguments are server hostnames or FQDNs to which to connect. The first one is used to make the initial session. All remaining ones are added to that session with tmux split-window -t $session.... At the end, we enable synchronized panes by default, so whenever you type, the commands will be sent to every SSH connection, thus allowing the neat ClusterSSH feature to run commands on multiple servers simultaneously. Once done, we attach (or switch, if already in Tmux) to it.

 Next, I plugged the Beelinks (one after another) into my monitor via HDMI (the resolution of the FreeBSD text console seems strangely stretched, as I am using the LG Dual Up monitor), connected Ethernet, an external USB keyboard, and the FreeBSD USB stick, and booted the devices up. With F7, I entered the boot menu and selected the USB stick for the FreeBSD installation.

 You might wonder why bother using the hosts file? Why not use DNS properly? The reason is simplicity. I don't manage 100 hosts, only a few here and there. Having an OpenWRT router in my home, I could also configure everything there, but maybe I'll do that later. For now, keep it simple and straightforward.

 The vm_delay isn't really required. It is used to wait 5 seconds before starting each VM, but there is currently only one VM per host. Maybe later, when there are more, this will be useful. After adding, there's now a Yes indicator in the AUTO column.

 The Linux benchmark is slightly slower than the FreeBSD one. The Go version is also a bit older. I tried the same with the up-to-date version of Go (1.24.x) with similar results. There could be a slight Bhyve overhead, or FreeBSD is just slightly more efficient in this benchmark. Overall, this shows that Bhyve performs excellently.

 The multi-CPU benchmark in the Bhyve VM ran with almost identical results to the FreeBSD host system. However, the memory benchmark failed with out-of-swap space errors. I am unsure why, as the VM has 14GB RAM, but I am not investigating further.

 The hostonly=no setting ensures the initramfs includes drivers for hardware not currently present. The use_devicesfile = 0 tells LVM to scan all block devices rather than only those recorded in /etc/lvm/devices/system.devices - this is important because the device path changes from /dev/vda to /dev/nvme0n1.

 To enable roaming clients (like earth and pixel7pro) to access the internet through the VPN, we need to configure NAT on the OpenBSD gateways. This allows the roaming clients to use the gateway's public IP address for outbound traffic. We add the following to /etc/pf.conf on both blowfish and fishfinger:

 The NAT rule translates outgoing traffic from the WireGuard network (192.168.2.0/24) to the gateway's public IP. The firewall rules permit WireGuard traffic on the wg0 interface and UDP port 56709. After updating /etc/pf.conf, reload the firewall:

Note that WireGuard does not support automatic failover between the two gateways (blowfish and fishfinger)—if one fails, manual disconnection and reconnection is required to switch to the other.

 The service is disabled from auto-start so the VPN is only active when manually started. This allows selective VPN usage based on need.

 In order to connect with kubectl from my Fedora laptop, I had to copy /etc/rancher/k3s/k3s.yaml from r0 to ~/.kube/config and then replace the value of the server field with r0.lan.buetow.org. kubectl can now manage the cluster. Note that this step has to be repeated when I want to connect to another node of the cluster (e.g. when r0 is down).

 Helm creates the infra namespace if it does not exist, provisions a PersistentVolume/PersistentVolumeClaim pair that points at /data/nfs/k3svolumes/registry, and spins up a single registry pod exposed via the docker-registry-service NodePort (30001). Verify everything is up before continuing:

 Thanks to the relayd configuration earlier in the post, the external hostnames (f3s.foo.zone, etc.) can already reach NodePort 30001, so publishing the registry later to the outside world is just a matter of wiring the DNS the same way as the ingress hosts. But by default, that's not enabled for now due to security reasons.

 Because every k3s node treats registry.lan.buetow.org:30001 as an insecure mirror (see above), the push succeeds regardless of which node answers. If you prefer the shortcut, just f3s in that directory performs the same build/tag/push sequence.

 Internally, Foostats::Logreader parses each line of the log files /var/log/daemon* and /var/www/logs/access_log*, turns timestamps into YYYYMMDD/HHMMSS values, hashes IP addresses with SHA3 (for anonymization), and hands a normalized event to Foostats::Filter. The filter compares the URI against entries in fooodds.txt, tracks how many times an IP address requests within the exact second, and drops anything suspicious (e.g., from web crawlers or malicious attackers). Valid events reach Foostats::Aggregator, which counts requests per protocol, records unique visitors for the Gemtext and Atom feeds, and remembers page-level IP sets. Foostats::FileOutputter writes the result as gzipped JSON files—one per day and per protocol—with IPv4/IPv6 splits, filtered counters, feed readership, and hashes for long URLs.

 The aggregator in Foostats aliases $self->{stats}{$date_key} before updating counters, so the structure remains intact. Combined with subroutine signatures, this makes it obvious when a piece of data is shared instead of copied, preventing silent bugs.

 Loki runs in single-binary mode with a single replica (loki-0), which is appropriate for a home lab cluster. This means there's only one Loki pod running at any time. If the node hosting Loki fails, Kubernetes will automatically reschedule the pod to another worker node—but there will be a brief downtime (typically under a minute) while this happens. For my home lab use case, this is perfectly acceptable.

 Auto-instrumentation is the quick win: one line of code and you get spans for every HTTP request, gRPC call, or database query. The instrumentor patches the framework at runtime, so existing code works without modification. The downside? You only get what the library authors decided to capture—generic HTTP attributes like http.method and http.status_code, but nothing domain-specific. Auto-instrumented spans also can't know your business logic, so a slow request shows up as "POST /api/search took 5 seconds" without revealing which internal operation caused the delay.

 The idea is that you describe the desired state and RCM worries about the steps. The given block can short‑circuit the whole run (for example, only run on a specific hostname). Each file resource can either manage a complete file (from a template) or just make sure individual lines are present.

 Ruby turns file into a method call and '/etc/hosts.test' into a normal argument. Inside RCM, that method builds a File resource object and stores it for later. The block you pass is just a Ruby block; RCM calls it with the file resource as self, so method calls like line configure that resource. There is no special parser here, just plain Ruby method and block dispatch.

 RCM uses Ruby's dynamic method lookup to interpret hostname and is in that block and to decide whether the rest of the configuration should run at all. Features like method_missing, blocks, and the ability to change what self means in a block make this kind of DSL possible with very little code. You still get all the power of Ruby (conditionals, loops, helper methods), but the surface reads like a small language of its own.

 Inside that block, calls such as hostname and is don't map to normal Ruby methods. Instead, RCM's DSL objects see those calls in method_missing, and interpret them as "check the current hostname" and "compare it to this symbol". This lets the DSL stay small and flexible: adding a new keyword can be as simple as handling another case in method_missing, without changing the Ruby syntax at all.

 RCM's real code is more sophisticated, but the idea is the same: Ruby happily calls method_missing for unknown methods like hostname and is, and the DSL turns those calls into a value (true/false) that decides whether the rest of the configuration should run.
