Sort of. "nix-store --delete <PATH>" will delete paths that refer to <PATH>, provided that those paths are themselves garbage, in order to make <PATH> deletable. But if you pass --ignore-liveness, the referrer closure will be deleted unconditionally. However, I do notice that the nix-store manpage incorrectly states that the existence of referring paths will prevent deletion. -- Eelco Dolstra | LogicBlox, Inc. | http://nixos.org/~eelco/ _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
