* nix: add options 'nixPath' and 'keepOldNixPath'
By default, the system value for $NIX_PATH is kept as a fallback.
To completely override the system value for $NIX_PATH:
nix.keepOldNixPath = false;
* nix: add more tests
* nix: add a declarative alternative to Nix channels
This adds a new option, 'nix.channels'. It's the Nix channels equivalent
of the 'nix.registry' option, and compatible with pre-Flake Nix tooling
including nix-env and nix-shell. Like 'nix.registry', this option is
useful for pinning Nix channels.
Channels defined in the new option can coexist with channels introduced
through the nix-channel command. If the same channel exists in both, the
one from Home Manager will be prioritized.
* nix: add news entry
* nix: make channels respect use-xdg-base-directories
* nix: remove 'with lib;'
