Actually, the output of “guix build” is indeed stored by default.
You can get it by asking for the logs for a given derivation.

For example:

    # build something, please
    guix build --no-substitutes samtools
    …
    # show me the derivation
    guix build -d samtools
    # show me the location of the matching log
    guix build --log-file $(guix build -d samtools)

Does this solve the feature request?
