To test your claim, I would suggest to write a manifest using package transformations [1] and then rebuild all Rust packages from Guix. 1: https://guix.gnu.org/manual/devel/en/guix.html#Package-Transformation-Op= tions 2: https://guix.gnu.org/manual/devel/en/guix.html#Defining-Package-Variants > Nevertheless, rebuilding all Rust packages on every rustc release > isn't strictly necessary. (Improvements in optimizations do happen, > but they are mosty minor release-to-release.) I do not understand how this could be implemented with Guix. Could you be more specific? Well, all in all, I do not think this report is a bug but a wish list. Instead, I would suggest to discuss the actionable tasks for updating Rust [3] in the mailing list guix-devel, WDYT? 3: https://guix.gnu.org/manual/devel/en/guix.html#Defining-Package-Variants Cheers, simon
