option

nix.buildMachines.*.sshKey

The path to the SSH private key with which to authenticate on the build machine. The private key must not have a passphrase. If null, the building user (root on NixOS machines) must have an appropriate ssh configuration to log in non-interactively. Note that for security reasons, this path must point to a file in the local filesystem, *not* to the nix store.
