Another argument in favor of this approach is verifiability, because
manifests record the argument to the ‘tune’ transformation option:
--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix shell eigen-benchmarks --tune
guix shell: tuning for CPU micro-architecture skylake
[env]$ guix package --export-manifest -p $GUIX_ENVIRONMENT
;; This "manifest" file can be passed to 'guix package -m' to reproduce
;; the content of your profile. This is "symbolic": it only specifies
;; package names. To reproduce the exact same profile, you also need to
;; capture the channels being used, as returned by "guix describe".
;; See the "Replicating Guix" section in the manual.
(use-modules (guix transformations))
(define transform1
(options->transformation '((tune . "skylake"))))
(packages->manifest
(list (transform1
(specification->package "eigen-benchmarks"))))
--8<---------------cut here---------------end--------------->8---
