From 8bc591a6f07ee577b5aa594dfa705f3ddabd269d Mon Sep 17 00:00:00 2001

Subject: * Use the copy-from-other-stores substituter by default.  Of course, 
  it only does something if $NIX_OTHER_STORES (not really a good   name...) is
 set. * Do globbing on the elements of $NIX_OTHER_STORES.  E.g. you could  
 set it to /mnts/*/nix or something. * Install substituters in
 libexec/nix/substituters.
