Been trying to cook up a systemd-sysext for crowdsec + crowdsec firewall bouncer to extend the base flatcar container linux image. Surprisingly straightforward with the sysext bakery.

However, crowdsec needs a mutable folder where it can write stuff (e.g logs etc.). This defaults to /var/crowdsec/data. I can create the /var/crowdsec/data folder but when crowdsec attempts to create and write to the logs folder below this I see a permission error.

Am I missing something obvious? Anyone know how I can fix this?

There was this lady in the coffee shop this morning with a bag her 10 yr old daughter made that had some art on it that reminded me of the CoreOS logo. What do you think?

@codingWombat Upstream with a tiny bit of layering ๐Ÿ˜….

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 ๐ŸŽ‰.

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.
