[Nix-dev] how to go about refactoring nixos-container?

[Rok Garbas]

my suggestion would be to start completely new project outside
nixos/nixpkgs and then if/when working then we can open an discussion
to replace nixos-container in nixpkgs.

and about the language. does it really matter. if you can do it in c++
that is currently preferred language in nix, but if you go the way i
suggested above and create new command line tool then it all depends
on you and your preferences. my current language of choice for cli
stuff is rust, but everything you'll choose is fine as long as the
tools is working :)

here are some name suggestions for new tools:
 - nixos-container-ng
 - nixos-container2
 - nixos-container-improved
 - nixos-kontainer

:)
