I do have some comments on the other questions.

Can I choose? >=20 It seems to me I usually get core and common packages as substitutes (binaries). There is the =E2=80=98--no-substitutes=E2=80=99 command line fl= ag to disable substitutes and always build from source. I can't see a flag for disabling source builds. You'll find this information in the guix info pages, specifically under "common build options" and "invoking guix system". > -Marco Thomas
