+synopsis: import-from-derivation builds the derivation in the build store
+prs: 9661
+---
+
+When using `--eval-store`, `import`ing from a derivation will now result in the derivation being built on the build store, i.e. the store specified in the `store` Nix option.
+
+Because the resulting Nix expression must be copied back to the eval store in order to be imported, this requires the eval store to trust the build store's signatures.
