Can someone tell me why #bootc is a replacement for #ostree? It seems like a solid downgrade.

Ostree has better download semantics, while bootc literally... clones container layers. Ostree lets you create temporary and permanent overlays. Bootc asks you to "maintain" your own container image. The temporary overlay solution is to use sysexts overlays, which is far more restrictive.

There are many other points that I'm forgetting right now.

So why is ostree being sunset in favour of bootc again?

Pobawiłem się jeszcze chwilę i okazuje się, że #zincati pozwala na ustalenie okna serwisowego, co chętnie zaaplikowałem do swojego modułu. No przyznam szczerze, jeszcze nigdy ustawienie okna patchingowego nie było dla mnie tak proste :-). Ustawiłem sobie okno w weekend, ale każde #zabbixproxy ma patching innego dnia.

Upgrading from #fedora #coreos 43.x to 44.x broke my podman setup, because apparently now:

- the first column in /etc/subuid and /etc/subgid must correspond to an existing user
- /etc/subuid and /etc/subgid must have a trailing newline

Probably a https://xkcd.com/1172/ situation, though.

Pierwszy update kontenerów i samego systemu za mną #FCOS
Update systemowy odbył się automatycznie, bez żadnych problemów, jedynie dostałem alarm z Zabbixa, że host został zrestartowany.
Dzisiaj miałem update #zabbix proxy do 7.0.27. Rano się obudziłem i już klaster pracował na nowej wersji obrazu. Bez żadnych dodatkowych tooli.

Digital Sovereignty isn't just for nations!

Now that the desktop has reached The Final Shape we turn attention to our homelabs.

Been making great progress on this, we're at v .8. This one is boring. Knuckle just installs flatcar.

But we want cloud native magic so we're building "Bluefin Server" but not sure on the name. And it'll run flatcar, and in there your magical bootc factory runs and your bluebuild just worked ootb. And the Fedora one will come with coreOS, tekton, forgejo, konflux, etc.

A place for both - if we design the homeserver and desktop as one unified WHOLE, we could do a ton more stuff. The tech is already finished.

Finally found the time to fix my #homelab server's Nvidia setup for #podman containers on Fedora #coreos 44.

Needed another repo for nvidia-container-toolkit additional to rpmfusion.

Fedora CoreOS zapowiada się na system operacyjny pod #selhosting który gdzieś wpisuje się w moje podejście do maszyn wirtualnych, czyli pod ciągłe tworzenie i ich usuwanie.
Udało mi się dostosować moduł #Terraform pod użycie CoreOS w Proxmox i pierwsza VM służy jako #zabbix proxy. #Butane przypomina #cloudinit co bardzo mi się podoba.

Ktoś może tutaj korzysta z CoreOS?

#fedora #fedoracoreos #coreos #fedoracore

I guess I can just stay on fedora-coreos:testing in these days 😅. Fast path to Kernel fixes.

#fedora #coreos

Had Nvidia GPU stuff working with rpmfusion on #fedora #coreos for a few releases.

Now in f44 the nvidia-container-toolkit package disappeared and my #podman containers that had AddDevice=nvidia.com/gpu=all set to gain access to the GPU won't start. Great.

@bhhaskin @nf3xn @Viss @mttaggart If your distro ships a kernel that allows it. #coreos and #fedora compile it as builtin and you can't unload it

I wonder how many other "cloud native" distros are in this situation?
