From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Thank you very much for your enlighten answer :D !
Yes that's what I found out with
apt show emacs-gtk, it shows all the dependencies but I found it quiet odd behavior (lack of knowledge).I wasn't aware of metapackages, something new to put into my knowledge database.
Edit: While writing my replay and searching through the web and my console, even though I wouldn't have had understood it while reading it... It actually tells me in the description that emacs is a metapackage... Bad reading skills :/ sorry about that !
If you don't mind I have a last question. Imagine I want to remove
docker-ce, which depends oniptablesamong others, if Isudo apt remove --purge --autoremove docker-ce, this isn't going to remove iptables and break my system right? Because it's used by other packages, system... I guess, no?I think a more general question would be how can I be sure I not going to fuck my system while removing packages? Maybe I'm to paranoïd and today it's relatively safe to do so, compared to years ago??
Thank you :)
If something else depends on it then it shouldn’t be removed, it’s only removing things that are not used elsewhere.
Usually just reading through the packages it’s listing and double check what it’s doing is enough. If something is removing a ton of gnome and you’re not trying to remove gnome, that would be an issue. If something is trying to remove the kernel (unless it’s an old kernel) or grub that’s also worth digging into. I’ve never run into problems with it, I don’t think it’s common these days.
