Re: [Nix-dev] nix on ubuntu/debian. replace core packages.
Even with hibernation it's not really possible to boot into another OS that quickly. If you want both systems running side by side it's probably easier to use a VM.

Re: [Nix-dev] nix on ubuntu/debian. replace core packages.
Hi Peter, When nix is installed on another distro what you get is a `~/.nix-profile/bin` installed in your PATH before the usual /usr/bin,/bin and so on. So if you install userland tools they will "replace" the system-provided ones just because the path lookup will find them first. So in that sense you get a unified userland between distros if you install the same nix packages. Does that answer your question? Note that this only works for userspace program and not system services.

[Nix-dev] nix on ubuntu/debian. replace core packages.
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.? /Peter ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
