This is really painful.

sudo nix --experimental-features 'nix-command flakes' --pure-eval build --profile /nix/var/nix/profiles/system -j 0 --builders-use-substitutes --builders 'ssh://myuser@20.191.64.192 x86_64-linux - - - big-parallel kvm' .#nixosConfigurations.xeep.config.system.build.toplevel

warning: Git tree '/home/cole/code/nixcfg' is dirty                                            
error: --- Error -------------------------------------------------------------------- nix

OK: sudo ssh myuser@20.191.64.192 true

OK: nix ping-store --store ssh://myuser@20.191.64.192

And:

> ssh myuser@20.191.64.192 systemctl cat nix-daemon.service | rg nix.conf
X-Restart-Triggers=/nix/store/zrf3g3mv44faz9zcwm8m0mw3bcg44s88-nix.conf

trusted-users = myuser

I don't get it. I'm in trusted-users, I and root can ssh with no prompt. And yet I am getting nothing but:

considering building on remote machine 'ssh://myuser@20.191.64.192'                                                                                   
hook reply is 'decline'                                                                                                                                       
wait for build slot 

What does it take to fix this bug? Is it conceivable that someone who doesn't know C++ could easily fix it? Or does this require pumbling the rejection over from the remote daemon?
