That is probably very distro dependent, I’m currently using bazzite on my daily driver and there the “updater” goes over absolutely everything: system images, custom dnf packages, containers, apt-get inside distrobox, flatpak… I guess also Android apps in way droid, but that I haven’t gotten into yet.
I lived seven years in Poland, somehow this sparks nostalgia ^^ I remember some news where passengers in a bus (crosscountry, not city) called the police because the driver seemed drunk… In the test he had like 4 promille.
