+Ce dossier contient un travail permettant de créer des dérivations qui
+vont toutes commencer par un préfix de taille et avec un nombre de
+composants donné (de la forme x/x/xxxxx)
+
+Le but étant de pouvoir copier une closure d’une dérivation, la mettre
+par exemple dans /opt/nix/store/....-foo et avec un simple `rename` +
+`sed` la rendre utilisable (dans l’exemple /nix/store/....-foo/xxx ->
+/opt/nix/store/....-foo).
+
+Ci dessous se trouvent des notes de ce que j’ai compris de la stack
+stdenv (pkgs/stdenv/linux/default.nix)
