Hey, > λ ./pre-inst-env guix system image -t iso9660 > gnu/system/install.scm --disable-authentication > guix system: error: disable-authentication: unrecognized option That's probably a side effect of https://issues.guix.gnu.org/53210 that includes the "current-guix" inside the installation image instead of the latest Guix snapshot. To build "current-guix", we rely on the channel-build-system and ultimately the latest-channel-instance procedure. This procedure takes an "authenticate?" argument. Now passing this option will be tricky as we do not call latest-channel-instance directly like in (guix scripts pull) but rather rely on the "current-guix" variable. I'll think more about it. Mathieu
