Hi, I built a new system w/ 'guix system' using Guix from Git v0.15.0-3115-g7571ec357 (please see below & sys.scm). But 'system reconfigure' fails when > 6 sites didn't have linux-libre-4.17.6 source (guix-reconfigure-linux-libre-4.17.6.log) This puzzles me ... Given that the system is built, why do we need to build linux now? Why can't I grep-find linux-libre-4.17.6 in the Guix working tree?
