[Command] Install on NixOS

[IvanChepurnyi]

Version of Warden

in-dev

Operating System and Installation Method

NixOS 24.11.712431.cbd8ec4de446 (Vicuna) via Git

Describe the Bug

Given that the NixOS partition is read-only changes to /etc/ directories are prohibited, so sudo tee to /etc/ssh/ssh_config fails during installation.

Although I can solve it with a workaround by modifying my /etc/nixos/configuration.nix with:

    programs.ssh.extraConfig = ''
	## WARDEN START ##
	Host tunnel.warden.test
	HostName 127.0.0.1
	User user
	Port 2222
	IdentityFile ~/.warden/tunnel/ssh_key
	## WARDEN END ##
    '';

It does not sound like a good option for me.

Is there any specific reason why warden does not place it into ~/.ssh/config instead?

To Reproduce

1. Execute recommended setup steps:

sudo mkdir /opt/warden
sudo chown $(whoami) /opt/warden
git clone -b main https://github.com/wardenenv/warden.git /opt/warden
echo 'export PATH="/opt/warden/bin:$PATH"' >> ~/.bashrc
PATH="/opt/warden/bin:$PATH"
warden svc up

Expected Behavior

No error messages are shown
