<para>Finally, if you can mount the Nix store of a remote machine in
your local filesystem, Nix can copy paths from the remote Nix store to
the local Nix store <emphasis>on demand</emphasis>. For instance,
suppose that you mount a remote machine containing a Nix store via
<command
xlink:href="http://fuse.sourceforge.net/sshfs.html">sshfs</command>:
<screen>
$ sshfs alice@itchy.example.org:/ /mnt</screen>
You should then set the <envar>NIX_OTHER_STORES</envar> environment
variable to tell Nix about this remote Nix store:
<screen>
$ export NIX_OTHER_STORES=/mnt/nix</screen>
Then if you do any Nix operation, e.g.
<screen>
$ nix-env -i firefox</screen>
and Nix has to build a path that it sees is already present in
<filename>/mnt/nix</filename>, then it will just copy from there
instead of building it from source.</para>
