I have nix installed, but can’t find nix-push anywhere.
Am I missing something? I need to backup and restore built derivations, and create a custom cache.
It looks like nix-push/pull got removed in favour of … nix-copy-closure? If so that doesn’t really do it unless it has some way to copy the closure to itself.
I’m in a container and want to save the closure for the next container to load. import/export seems to have an asterisk, as it did some, but threw a “derivation not found” error.
