Name¶

nix daemon - daemon to perform store operations on behalf of non-root clients

Synopsis¶

nix daemon [option…]

Examples¶

•

Run the daemon:

# nix daemon

•

Run the daemon and listen on standard I/O instead of binding to a UNIX socket:

# nix daemon --stdio

•

Run the daemon and force all connections to be trusted:

# nix daemon --force-trusted

•

Run the daemon and force all connections to be untrusted:

# nix daemon --force-untrusted

•

Run the daemon, listen on standard I/O, and force all connections to use Nix’s default trust:

# nix daemon --stdio --default-trust

Description¶

This command runs the Nix daemon, which is a required component in multi-user Nix installations. It runs build tasks and other operations on the Nix store on behalf of non-root users. Usually you don’t run the daemon directly; instead it’s managed by a service management framework such as systemd on Linux, or launchctl on Darwin.

Note that this daemon does not fork into the background.

Options¶

•

--default-trust

Use Nix’s default trust.

•

--force-trusted

Force the daemon to trust connecting clients.

•

--force-untrusted

Force the daemon to not trust connecting clients. The connection will be processed by the receiving daemon before forwarding commands.

•

--process-ops

Forces the daemon to process received commands itself rather than forwarding the commands straight to the remote store.

      This is useful for the `mounted-ssh://` store where some actions need to be performed on the remote end but as connected user, and not as the user of the underlying daemon on the remote end.

•

--stdio

Attach to standard I/O, instead of trying to bind to a UNIX socket.
