It sounds wonderful! Does anyone know other package managers suitable for Debian or Gentoo that allow handling packages on the 'per-user' basis? I'm really tired of sudo-ing every time I want to install a package for non-sudo user... This seems obsolete, redundant, and simply ugly. GUIX is definitely better in this regard, but what might be an alternative?
