/home/mycroft/.nix-profile/bin/hello
Note: ~/.nix-profile/bin was added in $PATH.
Prior to remove it, it must be unlinked from the profile and the build:
> nix-store --query --roots /nix/store/4nzxqrm1gddddwlz55c2q398p0si4qhf-hello
/home/mycroft/.local/state/nix/profiles/profile-7-link -> /nix/store/53zlkdqd1m2wdgi2a9q390ld9gkkkydf-profile
/home/mycroft/dev/nix-samples/result -> /nix/store/4nzxqrm1gddddwlz55c2q398p0si4qhf-hello
> nix profile remove /nix/store/4nzxqrm1gddddwlz55c2q398p0si4qhf-hello
removing 'hello'
>
It will be needed to wipe the profile history and the result link to be able to nix-store --delete or nix-collect-garbage.
