For the interested reader, the trick is to use...

--8<---------------cut here---------------start------------->8---
$ guix hash -f base16 $(guix build zabbix-agentd -S)
76cb704f2a04fbc87bb3eff44fa71339c355d467f7bbd8fb53f8927c760e1680
--8<---------------cut here---------------end--------------->8---

...but it must download.  Instead, I propose the patch#51307 which
