@codingWombat Upstream with a tiny bit of layering 😅.

No seriously, I like the local rpm layering. I don't depend on a (self hosted) CI pipeline to deploy updates and I don't mind having that long list of layered packages. This is a pet server, it only exists once and is properly backed up.

Today I learned: I don't need to put all my quadlets flat into containers/systemd, I can split them into subdirs 🎉.

That makes manually managing the ~50 containers (+volumes and networks) on my home server much clearer.

Fun fact: The best way to enable ptp_kvm on #coreos is ensuring the kernel arg ignition.platform.id=qemu is set. Then coreos-platform-chrony-config.service will load ptp_kvm and configure chrony accordingly.

rpm-ostree kargs --replace=ignition.platform.id=qemu

I was wondering why another VM at Ionos had ptp_kvm working without me setting it up. It turned out my Hetzner VM had ignition.platform.id=metal which prevents automatic ptp_kvm setup.

Inspired by @bycx I started looking into CoreOS which seems like a good OS for my home cluster (immutable, more lightweight than Debian, easier to maintain).

I'm starting with a simple process - installing from flash drive and providing the installer with prepared Ignition config file (generated with Butane). The process went through but upon booting I get "unsupported config version". And indeed, the config doesn't validate with ignition-validate because. As simple as this is, I cannot make it work. What am I overlooking?

UniFi OS Server installs just fine on Fedora CoreOS when doing "rpm-ostree usroverlay" before starting the installer.

This will allow it to create symlinks in /usr/bin which are not needed and don't need to be persisted. Without temporarily enabling usroverlay the installer will leave UniFi OS Server in a broken state.

Coreos is a great match for UniFi OS because the base system will upgrade automatically while application upgrades are managed by UniFi.

Aaaand it won't. Of course it wants to write in places where it's not even sane to write to on a mutable OS.

If you have some #Fedora #CoreOS `testing` stream nodes check them to see if they have stuck updates. More info and workaround steps in https://lists.fedoraproject.org/archives/list/[email protected]/message/ZMWF2EBO5ZBJE53MJFD75YID7XTNEGMB/

I've been wrangling with #fedora #coreos since yesterday to setup a minimal forgejo runner instance running in #podman. Although I've been working with Flacar Linux (the successor to the original CoreOS) before, it seems to behave a little bit different here and there (e.g. SELinux).

I successfully installed CoreOS using an ignition file served by the python3 simple http server.

I suppose it's against the spirit of the #coreos platform to manually add password authentication to the SSHd config, but that's what I did. For reasons I don't understand my SSH public key didn't work.

That's an exercise for later. Next step is to see what I can do with #fibrechannel
