[grahamc]

Was this connected to Ctrl-C or sending it another signal?

[marksisson]

no, just running:

export NIXPKGS_ALLOW_UNFREE=1 NIXPKGS_ALLOW_BROKEN=1 && caffeinate home-manager switch -b backup --flake .#$(whoami)@$(hostname) --impure

ran it again, and it was fine.

[marksisson]

this was the actual invocation:

just switch-home
export NIXPKGS_ALLOW_UNFREE=1 NIXPKGS_ALLOW_BROKEN=1 && caffeinate home-manager switch -b backup --flake .#$(whoami)@$(hostname) --impure
warning: Using 'builtins.derivation' to create a derivation named 'options.json' that references the store path '/nix/store/j04rrzm49kf2cjp4im0qz9zd4x4agbq0-source' without a proper context. The resulting derivation will not have a correct store reference, so this is unreliable and may stop working in the future.

Believe I've hit this issue as well, on macos Tahoe 26.3.1, nix version nix (Determinate Nix 3.16.3) 2.33.3. When running home-manager switch --flake .#<profile>:
