evdi akmod and DisplayLink support on Bluefin-based images after March 2025

Oh, and you may need to modify it a bit more to add the bazzite kernel from its repository. Not sure since I haven't tried it myself. https://github.com/ublue-os/kernel-cache/pkgs/container/bazzite-kernel

You could use this as a starting point: https://github.com/sukarn-m/sukarn-ublue/blob/main/files/scripts/coreos_kernel.sh Then set AKMOD_FLAVOR to "bazzite", and change the dnf lines to install the kmods that you want.

Is it suitable to create server images?

Quadlet configuration is comparable to defining a docker compose file. I don't keep those in sync using a central repository. i.e., there's nothing like a git pull or scp on each device to regularly fetch the latest version of those files from the NAS. If I change something on a device and it works as intended, I manually copy that change over into the butane/ignition on the NAS for future deployments. It's possible to make a method to update all configs on the NAS and fetch them on each device regularly, but that would be more of a hassle than convenience for my use-case. Containers, though, are pulled daily by each device in case an updated container image is available because of the line AutoUpdate=registry in the quadlet's .container file. See AutoUpdate= in https://docs.podman.io/en/latest/markdown/podman-systemd.unit.5.html for more information about this.

Butane/ignition give you the ability to create a file or folder on the device, define file contents inline in the butane/ignition or fetch the file from a link, and set its permissions. It also lets you enable or disable systemd services. I've used that to create a few scripts in /var/usrlocal/bin, systemd services in /etc/systemd/system and podman quadlets (.container and .volume files) in /etc/containers/systemd. Butane / ignition only runs at first boot. It does not run again.

Is it suitable to create server images?

No, I didn't bother with a method to keep the config on each device updated through a central repository. Once everything was fully set up about 1.5 years ago, changes became rare. I might make a one line change to the config here or there based on changing needs, or add or remove a podman quadlet from a device. In that case, I manually replicate that change onto the NAS after testing directly on a server. Each podman quadlet is set up to auto-update the respective containers using the quadlet configuration. Each podman quadlet is also set up to call the backup service as a timer for itself, which handles backing up the container volumes. Backups go into each device's separate directory on an NFS share on the NAS based on the hostname of each device. Old backups are deleted by the backup service automatically. SSH keys are signed weekly automatically using scripts and timers on both ends (NAS and each device), and they are set to expire after a few months.

I'm often in another city for weeks at a time, so it helps to just be able to give someone simple instructions to replace a card and turn it back on if tailscale shows any RPi is offline for a long time.

If a microSD card dies, I can just pick up any of the pre-ready cards, power off an RPi, replace the card in it, and turn it back on. It'll get restored from last night's backups and off it goes.

Along those lines, here's how mine is set up: - Main router set to assign static IP addresses to all RPi servers based on their MAC addresses. - Main NAS running a docker image of nginx-unprivileged, set up to redirect from NAS_IP/fetch.ign to ServerIP/hostname_based_directory/fetch.ign based on the visitor's IP address. One redirect set up in the config per RPi. - Multiple microSD cards, all with the same ignition configuration, set only to fetch NAS_IP/fetch.ign, which will get auto-redirected to the proper configuration for that particular device. - The overall ignition configuration is broken up into multiple files. Things like SSH configuration, user configuration, regular backup services, restore-from-backup services for first boot, and other common stuff, is imported into the configuration for all devices. Things like specific podman quadlets for each device are imported only into the specific servers that are supposed to be running them.
