I think that on GuixSD, the hosts file is generated from the system configuration, specifically the 'hosts-file' field, which is mentioned in section 7.2.2 Operating System Reference [0]. I assume that the resulting file is recreated each time you reconfigure. In that case, you'd want to leave the file /etc/hosts alone, and make your changes in the operating system configuration. I say "I think" and "I assume" because I haven't actually used 'hosts-file' yet, nor have I looked at that part of the code. Does that help?
