texliveGUST vs texliveFull

What is the difference between the two? The description seems rather uninformative.

probably not the best way but you could see the difference between them in the repl?

nix-repl> legacyPackages.x86_64-linux.texliveGUST.pkgs

#...paths                 

nix-repl> legacyPackages.x86_64-linux.texliveFull.pkgs         

#...more paths        

pkgs/tools/typesetting/tex/texlive/tlpdb.nix has the listings you are seeking for.

From what I understand now, it seems like GUST just contains less

Thanks, however, I’m still not completely sure what GUST is? I’m guessing it’s for something with polish? Is there any documentation why this gets its own scheme?

Yes, it seems to be a Polish acronym (?) https://www.gust.org.pl/index_html-en
