+# Filing a Nix issue
+
+*WAIT* Are you sure you're filing your issue in the right repository?
+
+We appreciate you taking the time to tell us about issues you encounter, but routing the issue to the right place will get you help sooner and save everyone time.
+
+This is the Nix repository, and issues here should be about Nix the build and package management *_tool_*.
+
+If you have a problem with a specific package on NixOS or when using Nix, you probably want to file an issue with _nixpkgs_, whose issue tracker is over at https://github.com/NixOS/nixpkgs/issues.
+
+Examples of _Nix_ issues:
+
+- Nix segfaults when I run `nix-build -A blahblah`
+- The Nix language needs a new builtin: `builtins.foobar`
+- Regression in the behavior of `nix-env` in Nix 2.0
+
+Examples of _nixpkgs_ issues:
+
+- glibc is b0rked on aarch64
+- chromium in NixOS doesn't support U2F but google-chrome does!
+- The OpenJDK package on macOS is missing a key component
+
+Chances are if you're a newcomer to the Nix world, you'll probably want the [nixpkgs tracker](https://github.com/NixOS/nixpkgs/issues). It also gets a lot more eyeball traffic so you'll probably get a response a lot more quickly.

-will call whenever it wants to build a derivation.  The build hook
-(typically a shell or Perl script) can decline the build, in which Nix

-<para>Nix ships with a build hook that should be suitable for most
-purposes.  It uses <command>ssh</command> and
-<command>nix-copy-closure</command> to copy the build inputs and
-outputs and perform the remote build.  To use it, you should set
-<envar>NIX_BUILD_HOOK</envar> to
-<filename><replaceable>prefix</replaceable>/libexec/nix/build-remote</filename>.
-You should also define a list of available build machines and point
-the environment variable <envar>NIX_REMOTE_SYSTEMS</envar> to
-it. <envar>NIX_REMOTE_SYSTEMS</envar> must be an absolute path. An
-example configuration is shown in <xref linkend='ex-remote-systems'
-/>.  Each line in the file specifies a machine, with the following
-bits of information:
+will try to connect to the machine named <literal>mac</literal>. It is
+possible to specify an SSH identity file as part of the remote store
+URI, e.g.
+
+<screen>
+$ nix ping-store --store ssh://mac?ssh-key=/home/alice/my-key
+</screen>
+
+Since builds should be non-interactive, the key should not have a
+passphrase. Alternatively, you can load identities ahead of time into
+<command>ssh-agent</command> or <command>gpg-agent</command>.</para>
+
+<para>If you get the error

+<warning><para>If you are building via the Nix daemon, it is the Nix
+daemon user account (that is, <literal>root</literal>) that should
+have SSH access to the remote machine. If you can’t or don’t want to

+e.g. <literal>--store ~/my-nix</literal>.</para></warning>
+
+<para>The list of remote machines can be specified on the command line
+or in the Nix configuration file. The former is convenient for
+testing. For example, the following command allows you to build a

+
+$ cat ./result

+
+It is possible to specify multiple builders separated by a semicolon
