-by a non-root user, which should be more secure<footnote><para>Note
-however that even when the Nix daemon runs as root, not
-<emphasis>that</emphasis> much code is executed as root: Nix
-expression evaluation is performed by the calling (unprivileged) user,
-and builds are performed under the special build user accounts.  So
-only the code that accesses the database and starts builds is executed
-as <literal>root</literal>.</para></footnote>.  Typically, this user
-is a special account called <literal>nix</literal>, but it can be
-named anything.  It should own the Nix store and database:
-
-<screen>
-$ chown -R nix /nix/store /nix/var/nix</screen>

-<screen>
-$ su - nix -c "exec /nix/bin/nix-daemon"</screen>

-<para>There is a catch, though: non-<literal>root</literal> users
-cannot start builds under the build user accounts, since the
-<function>setuid</function> system call is obviously privileged.  To
-allow a non-<literal>root</literal> Nix daemon to use the build user
-feature, it calls a setuid-root helper program,
-<command>nix-setuid-helper</command>.  This program is installed in
-<filename><replaceable>prefix</replaceable>/libexec/nix-setuid-helper</filename>.
-To set the permissions properly (Nix’s <command>make install</command>
-doesn’t do this, since we don’t want to ship setuid-root programs

-<para>Of course, the <command>nix-setuid-helper</command> command
-should not be usable by just anybody, since then anybody could run
-commands under the Nix build user accounts.  For that reason there is
-a configuration file <filename>/etc/nix-setuid.conf</filename> that
-restricts the use of the helper.  This file should be a text file
-containing precisely two lines, the first being the Nix daemon user
-and the second being the build users group, e.g.,
-
-<programlisting>
-nix
-nixbld
-</programlisting>

-The setuid-helper barfs if it is called by a user other than the one
-specified on the first line, or if it is asked to execute a build
-under a user who is not a member of the group specified on the second
-line.  The file <filename>/etc/nix-setuid.conf</filename> must be
-owned by root, and must not be group- or world-writable.  The
