[Nix-dev] nix on ubuntu/debian. replace core packages.

[Peter Holm]

My question is regarding  Nix multiuser-install.
Is it possible to replace the base-system with packages from nix.?
Or even better - boot to base-system from nix core, and keep desired
tools from the previous userland.?

My idea is simple - if its can be done. Then probably  one vould
ectand it to on-the-fly switch userland between distros and keep whats
installed from nix. Ok, you have to rebind or replace some
config-files... But , i belive  that should not be impossible to get
going.?
