- Fix missing SSH known_hosts in deploy pipeline
- SSH tries to use Trust-On-First-Use (TOFU) interactively to add a new
host key
- Verbose SSH logs show:
debug1: Server host key: ssh-ed25519 SHA256:1bbksDNYBWSh/rIFP7MMfs557kWn1dM64bpXdnfBE5E
debug1: read_passphrase: can't open /dev/tty: No such device or address
- deploy-rs uses nix, which uses SSH which doesn't use the environment variable
HOME, but rather /etc/passwd to find a user's HOME
- To solve this, we override SSH options using UserKnownHostsFile and
the -i flag
