Thank you for implementing.  I guix pull with the patch applied, add the IP
from

guix environment --ad-hoc bind:utils -- dig web.archive.org

to /etc/hosts, set my DNS server to a non-existing 10.0.0.50, disable
IPv6, then “sudo herd stop nscd”, re-connect Network Manager (ping
gnu.org fails now) and LC_ALL=en_US.utf8 guix install hello.  It
fails.  Did I misunderstand the patch’s purpose or test in a wrong
way?  This is the output:

florian@florianacer ~$ LC_ALL=en_US.utf8 guix install hello
The following package will be installed:
   hello 2.10
