[Nix-dev] Sharing the Nix store between systems

[Marc Weber]

Excerpts from Rickard Nilsson's message of Thu Sep 29 23:30:31 +0200 2011:

grep in nix source for nixbldX

patch nix or put references in /nix/var/nix/gcroots/..

If you have a client server setup there are remote builders. That's what
currently works. See manual and nix.buildMachines.
If you want to share the store so that you don't have to copy store
paths first before building I don't know about existing solutions yet -
but I'm interested in finding one as well.
