Oh, yes. The system configuration generated by the Guix 1.0 installer did not include %base-packages. The bug has been reported (https://debbugs.gnu.org/cgi/bugreport.cgi?bug=35541).

My packages form looks like this:

    (packages
        (list (specification->package "nss-certs")))

The Guix manual has been updated with instructions to work around the problem (https://www.gnu.org/software/guix/manual/en/guix.html#Preparing-for-Installation). So one should add:

    (packages
         (append (list (specification->package "nss-certs"))
                          %base-packages))

and then:

    guix pull && sudo guix system reconfigure /etc/config.scm


This may fix some of the bugs I've reported (and the ones I haven't).

Good to know. I'll go with the whole set, though.


Thanks, Mark.
