nix3-store...t-addressed(1) General Commands Manual nix3-store...t-addressed(1) Warning This program is experimental and its interface is subject to change. Name nix store make-content-addressed - rewrite a path or closure to content-ad- dressed form Synopsis nix store make-content-addressed [option...] installables... Examples * Create a content-addressed representation of the closure of GNU Hello: # nix store make-content-addressed nixpkgs#hello a| rewrote '/nix/store/v5sv61sszx301i0x6xysaqzla09nksnd-hello-2.10' to '/nix/store/5skmmcb9svys5lj3kbsrjg7vf2irid63-hello-2.10' Since the resulting paths are content-addressed, they are always trusted and don't need signatures to copied to another store: # nix copy --to /tmp/nix --trusted-public-keys '' /nix/store/5skmmcb9svys5lj3kbsrjg7vf2irid63-hello-2.10 By contrast, the original closure is input-addressed, so it does need signatures to be trusted: # nix copy --to /tmp/nix --trusted-public-keys '' nixpkgs#hello cannot add path '/nix/store/zy9wbxwcygrwnh8n2w9qbbcr6zk87m26-libunistring-0.9.10' because it lacks a signature by a trusted key * Create a content-addressed representation of the current NixOS system closure: # nix store make-content-addressed /run/current-system Description This command converts the closure of the store paths specified by instal- lables to content-addressed form. Nix store paths are usually input-addressed, meaning that the hash part of the store path is computed from the contents of the derivation (i.e., the build-time dependency graph). Input-addressed paths need to be signed by a trusted key if you want to import them into a store, because we need to trust that the contents of the path were actually built by the derivation. By contrast, in a content-addressed path, the hash part is computed from the contents of the path. This allows the contents of the path to be veri- fied without any additional information such as signatures. This means that a command like # nix build /nix/store/5skmmcb9svys5lj3kbsrjg7vf2irid63-hello-2.10 \ --substituters https://my-cache.example.org will succeed even if the binary cache https://my-cache.example.org doesn't present any signatures. Options * --from store-uri URL of the source Nix store. * --json Produce output in JSON format, suitable for consumption by another pro- gram. * --no-pretty Print compact JSON output on a single line, even when the output is a terminal. Some commands may print multiple JSON objects on separate lines. See `--pretty`. * --pretty Print multi-line, indented JSON output for readability. Default: indent if output is to a terminal. This option is only effective when `--json` is also specified. * --stdin Read installables from the standard input. No default installable ap- plied. * --to store-uri URL of the destination Nix store. Common evaluation options * --arg name expr Pass the value expr as the argument name to Nix functions. * --arg-from-file name path Pass the contents of file path as the argument name to Nix functions. * --arg-from-stdin name Pass the contents of stdin as the argument name to Nix functions. * --argstr name string Pass the string string as the argument name to Nix functions. * --debugger Start an interactive environment if evaluation fails. * --eval-store store-url The URL of the Nix store to use for evaluation, i.e. to store deriva- tions (.drv files) and inputs referenced by them. * --impure Allow access to mutable paths and repositories. * --include / -I path Add path to search path entries used to resolve lookup paths This option may be given multiple times. Paths added through -I take precedence over the nix-path configuration setting and the NIX_PATH environment variable. * --override-flake original-ref resolved-ref Override the flake registries, redirecting original-ref to resolved-ref. Common flake-related options * --commit-lock-file Commit changes to the flake's lock file. * --inputs-from flake-url Use the inputs of the specified flake as registry entries. * --no-registries Don't allow lookups in the flake registries. DEPRECATED Use --no-use-registries instead. * --no-update-lock-file Do not allow any updates to the flake's lock file. * --no-write-lock-file Do not write the flake's newly generated lock file. * --output-lock-file flake-lock-path Write the given lock file instead of flake.lock within the top-level flake. * --override-input input-path flake-url Override a specific flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock-file. * --recreate-lock-file Recreate the flake's lock file from scratch. DEPRECATED Use nix flake update instead. * --reference-lock-file flake-lock-path Read the given lock file instead of flake.lock within the top-level flake. * --update-input input-path Update a specific flake input (ignoring its previous entry in the lock file). DEPRECATED Use nix flake update instead. Logging-related options * --debug Set the logging verbosity level to `debug'. * --log-format format Set the format of log output; one of raw, internal-json, bar or bar- with-logs. * --print-build-logs / -L Print full build logs on standard error. * --quiet Decrease the logging verbosity level. * --verbose / -v Increase the logging verbosity level. Miscellaneous global options * --help Show usage information. * --offline Disable substituters and consider all previously downloaded files up-to- date. * --option name value Set the Nix configuration setting name to value (overriding nix.conf). * --refresh Consider all previously downloaded files out-of-date. * --repair During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths. * --version Show version information. Options that change the interpretation of installables * --all Apply the operation to every store path. * --derivation Operate on the store derivation rather than its outputs. * --expr expr Interpret installables as attribute paths relative to the Nix expression expr. * --file / -f file Interpret installables as attribute paths relative to the Nix expression stored in file. If file is the character -, then a Nix expression is read from standard input. Implies --impure. * --recursive / -r Apply operation to closure of the specified paths. Note See man nix.conf for overriding configuration settings with command line flags. nix3-store...t-addressed(1)
