You can add '--gc-keep-outputs=yes' and '--gc-keep-derivations=yes'
flags to guix-daemon in 'guix-daemon.service' (assume you are using
systemd as init).

The relevant info can be found in
<https://www.gnu.org/software/guix/manual/guix.html#Invoking-guix_002ddaemon>.

Hope it helps, it was the question I asked on this list in the past!
