Hi, this is a background question. I've googled a bit around, but I didn't find a suitable resource. Do the GRUB entries, which you can see an choose of during the boot process, mean, that all old package versions ([package-name].f20|f21|f22.[...]) are kept on disc? (This is, what I'd guess firstly.)

Is there a more or less easy way to manage this, because I don't have thaat much space on disc?

Welcome to ask.fedora. Your question has been asked and answered here many, many times, and searching the forum for GRUB will probably bring them all up for you.

To answer your question, by default, Fedora keeps the three most recent kernels, removing the oldest versions as needed. This means that if something goes wrong and the newest kernel doesn't boot, or breaks something, you always have two backups to try, both known to be good. And, this is why the instructions say that if you're using a separate partition for /boot it needs to be at least 500 MB in size, because there has to be room for the newest kernel and its associated files to be installed before the oldest is removed. (If you're not using a separate /boot, don't worry; there's no need to, and I haven't used one in almost a decade.)

If the above doesn't answer all of your questions on this issue, feel free to add a comment asking for further information, because we're here to help you, not just tell you to use the search function and close the question without actually helping you.
