Activate remote machines locally from mac

Work on my primary machine (macOS) and remotely activate new configuration for Linux machines and such.

[srid]

or,

nix run nixpkgs#nixos-rebuild -- switch --fast --flake .#pinch --target-host root@pinch --build-host root@pinch

This works for non-trivial configurations:

nixos-config/justfile

Lines 4 to 9 in 0196461

	# Remote deploy to a host
	remote host='here':
	nixos-rebuild switch --fast --use-remote-sudo \
	--flake .#{{host}} \
	--target-host $USER@{{host}} \
	--build-host $USER@{{host}}

But not when using certain packages, like nixvim:

Per nixos-rebuild(8), you may wish to consider dropping "--fast"

       --fast  Equivalent to --no-build-nix.  This  op‐
               tion is useful if you call nixos-rebuild
               frequently  (e.g. if you’re hacking on a
               NixOS module).

I'd think --fast actually helps. If I remove it, it will try to build the Linux configuration on macOS (not what I want),

Note that, if --no-build-nix is not specified, Nix will be built
both locally and remotely. This is because the configuration will
always be evaluated locally even though the building might be per‐
formed remotely.

Indeed, when I remove it - the deployment from mac does fail:
