Pretty much, except "every time" is really less often than expected, because the gitlab runner can cache files between jobs. So with an appropriate tar command, it is possible to pack the whole store plus the /var/guix and untar it at the beginning of the job (or re-run the guix install if the cache has been dropped). Or run "guix pack". There is a very unfortunate problem that running "guix pull" or guix installing something will require the "ntp" debian package, so each job requires apt-get update and apt-get install -y ntp... I am investigating how to cache the ntp package (and its dependencies) to avoid running apt-get update, but that's quite disappointing. divoplade
