This mounts an arbitrary Nix store on the specified mount point. Typical usage: $ /nix/store/d0am5d8gwh2kfdcgyxh4y684mb5b2v54-blender-2.79/bin/blender --version bash: /nix/store/d0am5d8gwh2kfdcgyxh4y684mb5b2v54-blender-2.79/bin/blender: No such file or directory $ nix mount-store /tmp/mp --store https://cache.nixos.org?local-nar-cache=/tmp/nars $ unshare -m -r $ mount -o bind /tmp/mp /nix/store $ /nix/store/d0am5d8gwh2kfdcgyxh4y684mb5b2v54-blender-2.79/bin/blender --version [after a lot of downloading...] Blender 2.79 (sub 0) One application is to replace the current remote store file access in hydra-server implemented via "nix {cat,ls}-store", which doesn't work all that well (e.g. it doesn't resolve symlinks properly). Another application would be on-demand fetching of build inputs on Hydra build slaves (to speed up builds that don't access their entire closure). However, that will require a lot more machinery.
