I see how Guix bundles are built. I think, Proot is a better way than `guix fhs`.
/ --- Гну Линьг Рут (-u-). /home/tldr/debian --- Joe's FHS (./bin, ./usr, ...) `proot -R /home/tldr/debian`. `wget tor-browser-why-not`. `./sus-shady-run`. Proot is a user-process. It should do GUI apps well (worked for Nixo McTest). Still want FHS maded with Scheme (if it is possible to link against /lib inside...).
