Another way would be to create a small derivation that copies the default tor derivation, overwrites the etc folder and then use that as your system Tor. (See runCommand)

environment.systemPackages =
let
  my-custom-tor = pkgs.runCommand "my-custom-tor" {} ''
          mkdir $out
          cp -r ${pkgs.tor}/* $out/
          chmod -R 755 $out
          echo "config" > $out/etc/tor/torrc
          ''
in
[
...
my-custom-tor
...
]

Because no person in my life uses it I made the generalization that it isn't used much, leading to my top comment.

The point is to take the base communication technology (texting) and bring it to the 21st century without being beholden to some American company.

Is this satirical? RCS is beholden to some American company as far as I can tell.

They still need an RCS client on PC, etc.
All the apple users I know use WhatsApp, Signal, telegram and not one uses IMessage, not even the company I work at, which uses iPhones mainly, uses IMessage for communication, private or otherwise.

I guess so? I haven't met anyone who's using sms for that but apparently that's just regional.

It's going live in a few months iirc.

Yeah you need a TrickyStore and a valid key, though my point is that they can pick and choose who can be an RCS client.

Did you expect it to ever get better? Best google can do is kill background apps without your permission.

So we're back to square one, five messengers and one which "can do anything"©®™ led by google. No thanks I'd rather let SMS be as it is.

As far as I can see you can't join the network without some kind of authorization (see rooted phones being unable to).

No, I'm saying that there isn't. You can use all those things on every platform, RCS would be the 6th program you need to install besides the other 5 you already have and it seems useless compared to the rest.

Edit: platform as in android, windows, iOS etc

Rust/linux^Rust^

As far as I can see you don't define any way to start Tor in nix but that is how nix normally passes along the tor config.
ExecStart=/nix/store/<hash1>-tor-0.4.8.14/bin/tor -f /nix/store/<hash2>-torrc
ExecStart=${pkgs.tor}/bin/tor -f ${localTorrcDefinition}

You could define a file in etc that is your torrc, then point your service manager to use that as the -f argument for Tor.

Another way would be to create a small derivation that copies the default tor derivation, overwrites the etc folder and then use that as your system Tor. (See runCommand)

Straight to jail.
