Good thing I moved all my repos from git[lab|hub] to Codeberg recently.

It started with Red Hat 6.1 in 1999 and ended up with NixOS.

This really sounds like BS: Poland has zero running nuclear power plants for power production. They run one experimental reactor, have no existing infrastructure or notable experience.

It would take around 6-15 years to build one power plant, would cost 5-20 billion € per power plant and where would fuel come from, where would waste go?

Or a simple “Na” while pointing to your nether region will do as well.

You have two options to switch to systemd-boot on Fedora:

Use inst.sdboot as kernel parameter while installing Fedora, see https://fedoraproject.org/wiki/Changes/cleanup_systemd_install

Or use conversation scripts systemd-boot-conversion provided by Sebastiaan Franken

I used the script for two of my installations without any issues: systemd-boot-install-fedora-no-secureboot.sh
