Question: home-manager switch --flake create a new "nix profile generation" with standalone installation

[cloud-yu]

I'm using standalone home-manager, in dir ~/.local/state/nix/profiles i found two type of generations, home-manger for "home-manage" and profile for "nix profile".
Each time i use home-manager switch to build a new generation or rollback to a prior generation, a new generation for nix profile will be generated.

In this figure

• initial state is "hm-9-link" and "prof-1-link"
• after ahome-manager switch, it generated "hm-10-link" and "prof-2-link"
• after a home-manager switch --rollback, a new "prof-3-link" generated.

and nix profile history says no change.

Since I'm using home-manager take over my user envrionment, i don't need nix profile any more. Is it possible to disable nix profile ?

Unfortunately no. The regular user profile is difficult to avoid. In principle it may be possible to have Home Manager take it over completely but it would break standard profile commands such as nix profile add, which seems quite bad.

I think that we have to keep the user profile for the foreseeable future.

Maybe make it be a optional choice ? Since most people use either HM or regular user profile, these two can be mutually substituted.
