I agree. It would ease the dance. In addition, it would help to have a subsection in the manual about "cross-compilation"; maybe under the Development section. For instance, I do not find clear the difference between 'system' and 'target'. And the explanations for the triplet are outside the Guix manual, pointing to [1] which I do not find very clear. Something like an explicit list of possible values for this triplet would be worth. 1: <https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.71/autoconf.html#Specifying-target-triplets> Cheers, simon
