The stores in $NIX_OTHER_STORES must have the same "true" location (i.e.
/nix/store), so they can be used for binary deployment.  They idea is that
they're NFS mounts (or similar) of the /nix/store on another machine.  The NixOS
installer uses it to copy stuff from the /nix/store on the installation CD (so
/nix/store is bind-mounted into the target chroot).

Note however that currently NFS mounts don't work due to SQLite issues.
