The only thing that ab= orts a > build phase now is an exception. I would be glad if this were the case, but I believe you're mistaken. On both master and core-updates, in (guix build gnu-build-system), the 'gnu-build' procedure iterates over the phases using 'every', and procedure passed to 'every' ends by returning 'result', which is the value that the phase returned. Am I missing something? Regards, Mark
