@lunacb >the average "gnu/linux" installation is hardly just gnu and linux though, right? I'd say the gnu part is usually the minority, actually.
It depends. The highest tier of GNU/Linux is all GNU software with GNU Linux-libre - it's almost all GNU.
Linux still is the minority compared to GNU still on average systems.
If you want to call it systemd/X11/libreoffice/chromium/GNU/Linux, go ahead.

>If you were to take most people's linuxes and remove everything that isn't gnu or linux, it probably wouldn't even boot, and it definitely wouldn't be a practical for anything people would expect of a modern operating system.
Please immediately cease referring to the GNU OS as "Linux".

On the OS's I use, you could remove all the non-GNU software, aside from the init and the computer will still boot and provide most of that I expect from an OS (everything is just a bootloader for emacs).
Meanwhile if you were to remove GNU, you'd have a far inferior experience (Alpine BusyBox/Linux really sucks until you install GNU for example).

On Guix, if you were to delete everything non-GNU (it uses GNU Shepard as the init and GNU Linux-libre), it'll boot just fine really and maybe you wouldn't even notice if you're a based emacs in the tty user (like rms).
