<listitem><para>This variable contains the paths of remote Nix
installations from whichs paths can be copied, separated by colons.
See <xref linkend="sec-sharing-packages" /> for details. Each path
should be the <filename>/nix</filename> directory of a remote Nix
installation (i.e., not the <filename>/nix/store</filename>
directory). The paths are subject to globbing, so you can set it so
something like <literal>/var/run/nix/remote-stores/*/nix</literal>
and mount multiple remote filesystems in
<literal>/var/run/nix/remote-stores</literal>.</para>
<para>Note that if you’re building through the <link
linkend="sec-nix-worker">Nix daemon</link>, the only setting for
this variable that matters is the one that the
<command>nix-worker</command> process uses. So if you want to
change it, you have to restart the daemon.</para></listitem>
