Layering packages with rpm-ostree from Kickstart

The idea is to be able to run rpm-ostree install <package> from %post section of the Kickstart.

Currently it doesn’t work for me,
if I run following in Anaconda console just after system install (but before reboot), get an error:

[anaconda root@fedora ~]# rpm-ostree status --sysroot=/mnt/sysroot/
Job for rpm-ostreed.service failed because the control process exited with error code.

See "systemctl status rpm-ostreed.service" and "journalctl -xeu rpm-ostreed.service" for details.

Please don’t ping me personally for help on discussion threads. I already watch questions that are tagged Silverblue, etc.

In this case, you can not do that as the system is not booted via (rpm-)ostree so the daemon won’t start. You should layer packages on first boot.

Thanks. Please note I’m chasing fully scripted installation, though.
Does Anaconda provides abilities to schedule some commands for the first boot, maybe?

Other possibility that comes to mind is try to create systemd One-time service..

Or what I’m asking for is more naturally solved with Ostree Native Containers by ostreecontainer Kickstart verb?

If you have internet access, you can write a systemd unit that runs on first boot and does the layering.

If you don’t, then you would have to re-create a full ISO using your own composes / commits. This is not super ergonomic to do right now.

I have WiFi internet only which I already scripted Network Manager configuration for.
Now only thing left is to approach systemd run my one-time unit after WiFi is set up..

… and we have the facility:

So I ended up with the following.. workaround Kickstart snippet:

%post --erroronfail

mkdir -p /usr/local/lib/systemd/system
cat > /usr/local/lib/systemd/system/rpm-ostree-init.service << 'EOF'
