Install zstd and/or nix on chi-node-14
Using my shell access to access /srv/shadow, I can't easily inspect the archived experiment results there because they're zstd-compressed.
Installing zstd would solve my immediate problem.
I'm also learning about and starting to experiment with nix. IIUC once installed, unprivileged users can install nix packages in their local environment. This would probably save some headaches of having to file an issue to install an incidental package like zstd :)
