Until now, 'current-guix-package' was parameterized in the wrong context. Thus, 'current-guix' would end up building a variant of the 'guix' package instead of the package returned by 'channel-source->package', which is much less expensive to build. * etc/system-tests.scm (mparameterize): New macro. (tests-for-current-guix): Change the 'value' field of each <system-test> record to parameterize 'current-guix-package' for good.
